My 1976 Chevy Blazer K5, runs and drives excellent. But when I take it up into the mountains 4 wheeling, there is a problem. Any time that one or the other of the front tires goes up on a hill and there is any twist to the frame, I get this constant grinding noise. If I stop and put it in park, it still grinds and wont stop until the front tires on the same plane. What could this be?
View 1 RepliesWe've had a lot of rain here in pa lately and i hit a few big puddles the other day and now i have a growl slash wine in the front of my motor,now i narrowed it down to something driven by the bely because I removed the belt and no noise all pulleys feel good and smooth except the ac compressor if you spin it by hand it has a rough/dry feeling and sound to it but the noise doesn't change with the ac on or off its just constant grinding/whine. Replace the ac compressor pulley bearing that what I am thinking it is and don't really want to change out the whole compressor..
View 1 RepliesMy 4WD light does not come on but the warning light to service it does which leads me to believe the 2WD is not engaged. I have a 2001 Chevy Blazer. Also the seems to be a "rubbing" noise emanating from the right from while driving.
View 1 Replies1997 chevy balzer 4.3 6cyc. Oil pressure drop from 40 to 10 and making a knocking sound no loss in power. About 3 weeks ago had oil change and new oil lines and gaskets put on because i had some leaks no noise or problems then just was losing oil then this happened first of all does this sound like a main bearing gave away second should i go back to where i had this work done and complain could they have done something to cause this they are very good and honest mechanics and a reliable auto repair mechanic company the blazer has 180,000 miles or do you think it just because of the mileage it was bound to happen i hate to blame something on someone if was just a coincidence but does this sound like the main bearing?

In the last couple of weeks, if the Blazer isn't driven for 3 or more days, there is a slight knocking noise for 15 to 20 seconds after start up. Oil level and pressure are fine. I'm guessing it's the lifters.....
I have a 2001 F350 with a7.3 power stroke, 6 speed manual with manual t case and hubs. I have a bad grinding noise when in 2 wheel drive. Similar sound as if you are trying to shift t case into 4 wheel drive too slowly. The grinding is constant in 2 wheel drive, but if I shift it into 4 wheel drive, the noise completely goes away. I have been driving around in 4 wheel drive (T case only, manual hubs not locked) for the past 2 days. If I shift back into 2 wheel drive, a constant terrible grinding noise returns. What could be wrong, and why it goes away in 4 wheel drive?????
View 3 RepliesI "think" I may have a bad wheel bearing. Problem is, which one is it? The code reader I own does not read for ABS. The noise appears around 30 mph. It increased slightly, at higher speeds. I tried jacking each side of the truck up and checking for play and noise. There is no play. The only thing I can say is that the passenger side wheel seems heavy to spin. But spins.
The drivers side wheel spins slightly more free, but has a faint sound like the brake shoe is touching the rotor. I drove it and tried turning left and right. The noise does not seem to get worse or better when turning either direction. I called my local Auto Zone, and they only told me to do what I have already done. So I am at a loss. What else can I do? My Blazer is a 2000, 4X4, Automatic.
Think i have an exhaust leak in a 1999 s10 blazer lt 4x4 4 door. the loudest spot where i can hear the exhaust noise at cold start and idle, is the passenger side right behind the front tire. on cold mornings where you can see the exhaust smoke prior to warming up i cannot see anything coming from this area. non mechanic types have suggested either the y pipe, or where the y pipe meets the header. Would both have to be replaced to fix this problem if this is the case? and how intensive is this to fix? meaning would the whole motor have to be pulled to remove the entire exhaust piping to have it brazed? my dad is a mechanic, so the tools I've got and his know-how, just need to know what to do? Any definitive way to tell where an exhaust leak is, beyond having a friend cup their hand over the tail pipe, while they look for it..
View 3 RepliesImmediately after I had four new tires installed on a 2000 Blazer 4wd, the front wheel bearings started making noise. At the time I thought the noise was from the new tires. A few thousand miles later my mechanic told me I needed two reman hub assemblies (sealed bearings) for ~$350 apiece plus labor.
Is there anything that the tire shop (independent not chain) could have done (accidentally or otherwise) to damage the bearings during the tire installation? I have to get 4 tires for my 93 Chevrolet Caprice and don't wish to repeat the experience.
Whoops, forgot to mention this happened at 56k miles when the truck was five years old. Is it possible that the bearings were borderline and the process of mounting the wheels put them over the edge? For instance, someone being a little over enthusiastic with an impact wrench.
For about a year and a half I have had an "undiagnosable" noise that started as an intermittent metallic buzzing and has evolved into a constant whirring/grinding noise. The tempo of the noise increases when accelerating; occurs at all speeds and at idle. People say they know when I am approaching they can hear my car from about two blocks away.
My regular 20 year mechanic checked transmission, replaced timing belt (at 65K; now have about 74K); all idler pulleys; checked alternator; He thinks is is the AC drive pulley on the compressor; Hyundai dealership did not know what it is; laymen have suggested is is a power steering pump, reservoir issue. Power steering fluid level is fine. Otherwise, the performance of the car is fine.
Engine is 3.5L V6; 2004, about 74+K

Recently had my AC compressor assembly replaced, renewed accumulator/receiver drier, orifice tube, recharge, etc. The AC was cooling well below par after the repairs. Then is started alternately blowing hot (12 sec), cool (3 sec), etc. with a "spooky" creaking noise coming from within the middle dash during each transition (blend door?).
The mechanic charged the system again and agrees there is a refrigerant leak "somewhere" to account for the marginal cooling capability but the dye put into the system before the repair is not showing up anywhere that he can see (so far, having it checked again today). So, are these 2 separate issues? What are the steps of diagnosis and repair possibilities?
My belt was making a screaming squeaky noise to wake up the dead. I used dish soap on it and it got quiet as long as I remember to bring the dish soap. My mechanic looked at my AC and told me I need a new compressor (he is a friend I trust) Now the AC comp turns but the belt seems to go on and off. And, the weird thing is-the AC feels great! Am I to expect any moment for it to just stop working? So, what to expect from my dead or dying compressor?
View 18 RepliesActually above + an interesting mystery.. Late last spring I began hearing a noise of constant pitch (sounding like someone sanding wood) when the engine was cold---Louder when it was colder/cooler. As the engine warmed up the noise went away. Throughout the summer,No Noise. n. Late summer broken water pump replaced along with hoses/belts. No noise until, temps in AM in the 40's.
Now that same damn noise is back.Only LOUDER! Same pattern>>as engine warms noise softens and goes away. My ear suggests noise is coming from the tensioner pulley (But, I've been fooled before)As to the question above, Do I tighten the belt on 'This vehicle' using the tensioner pulley or do I have to use the "Pry the Alternator forward" method.? One last thing, while the noise is occurring it does get louder with acceleration but is soon blocked out by normal engine noise.
Year: 1999Make: Chevrolet
Model: Silverado 1500 LS
Issue: Bad Transfer Case
Late model 99 Chevrolet Sliverado 4x4 with push button transfer case. At the end of last winter the transfer case began a grinding-noise when attempting to go from 2H to 4H.
I have a great mechanic who has proven both his skill and honesty to me a few times now. I took the truck in for diagnosis. His hope was that the electronic transfer may be faulty but unfortunately found metal shavings when he went to check the lubricant in the transfer case.
Diagnosis: Bad Transfer Case - Replacement necessary.
Mechanic has recommended a salvaged transfer case from reputable salvage dealer.
I have sourced a rebuilt transfer case with manufacturer warranties from a "major parts chain" for approximately 1/3 more cost.
My debate: The truck (while very late model), has a rebuilt engine that has less than 50k miles on the rebuild. I have expectations that I will continue to drive and maintain this truck for a very long time.
Although I am always aligned with less cost, my first response is that the rebuild from "major parts chain" is warrantied and far less likely to require a replacement in the remaining life of the vehicle.
However I am also uncertain how to evaluate the existing transmission. Presumably it has >100k. Is there a risk in pairing an OEM rebuilt transfer case with a transmission this old?
I have an 04 Chevy Venture. Recently it started making what I can only describe as a grinding. I have been a mechanic for over 30 years, working on everything from motorcycles to heavy construction equipment. This is a new one on me. I have checked the wheel bearings, brakes and rotors, and suspension. All good. I have blocked her up and put it in gear, and the noise seems to be coming from the transaxle. Fluid is cherry red and is not burnt, no metal shavings, and not low. I have noticed that while driving, if I jog the wheel left or right, it quite until you straighten out again. If I weave back n forth going down the road, it's pretty much non existant, but the cops are starting get suspicious.
View 6 RepliesI drive a 2001 Chevy Prizm with 90,000 miles on it. Lately, when I'm accelerating over about 30 to 40 mph, my engine starts to make a grinding noise, that gets worse the faster I go, or the more pressure I apply. The noise also happens when I'm going up hill. What's causing this noise, so I don't look like an idiot when I take it in to my mechanic?

View 5 RepliesAbout 5 years ago, my air conditioner started making a metallic-sounding grinding noise, when it is turned OFF. This noise goes away if the A/C is on. My mechanic said some part was slightly bent, bent it back, and this fixed it for a while. Eventually the noise came back but was intermittent. I drove the car for years hoping it would go away, leaving the A/C on most of the time. The noise is no longer intermittent, and my new mechanic says that it seems louder than before and if I don't get it fixed, it might cause the car to stall out. He offered to bypass it with a belt or replace the unit. What this could be? I drive with the A/C on now. 1998 geo prizm
View 3 RepliesI have a 1987 Camaro with a 305 TPI V-8, with a 5-speed manual transmission. I rebuilt the transmission, and installed a new clutch, pressure plate, throw out bearing, and had the fly wheel ground (which the machine shop said that it took very little material off to get clean-up). When we first got the car running when the car is moving in any gear (even in neutral) with the clutch peddle down, I get a rotary grinding noise (but only about 30% of the time). If I let the clutch pedal up the noise stops immedately. The transmission shift smooly, in all gear selection. I thought that I had gotten a bad throw out bearing, so we installed an other new throw out bearing, but I get the same noise. Is there something that could cause this noise inside the transmission?
View 8 RepliesI have a 2005 Chevy Malibu, automatic transmission. When I put it in reverse and then press the gas pedal, I get a rather loud grinding noise for a couple of seconds. What is causing this, and is it doing any real damage? I have no other problems with the transmission.
View 2 RepliesAfter driving for about 15 minutes, once it is warmed up, at acceleration & low rpm's, there is a vibration, mild grinding noise. Once you get to mid-range and up on the rpm's, it goes away. When cruising down the highway at normal speeds and a consistent rpm...no noise. Idling at, and taking off from a stop light, I get the noise. The longer it is driven, the more noticeable the noise is. Possible torque converter?
