Passat (B6) :: Shuttering In Front End When Go Over Harsh Bumps - Bad Engine Mounts?
Oct 10, 2013
I have a 08 2.0T sedan with 97K that I have been chasing a "shuttering" feeling in the front end when I go over harsh bumps like railroad tracks and frost heaves that we get on roads here in NE.
At this point the front suspension has had a lot of improvements done and problem still exits.
Front suspension work over last 6 months:
- New LCA Bushings (solid rubber style rear and Whiteline front)
- Koni FSD Shocks
- VW DG Sport Springs
- 034 Density upper strut mounts
- Meyle HD Sway Bar Link
- ECS Sub Frame Bolt Kit
After all this there is actually an increase in this shuttering feeling most likely due to a firmer suspension now with new springs.
The car drive fantastic, the feeling that there is something loose up front and the shuttering feeling when hitting harsh bumps is diving me crazy.
In addition, I drove a local VwVortexer's 06 Passat that is riding low on coilovers and it did not have this same shuttering from the front so pretty sure what is going on in my car is not normal.
Completely went through front suspension last night and tripled checked that everything is tight and secure!
Also, have upgraded sub frame bolts with ECS kit and checked all the bolts to make sure they are tight and all is good.
Since after all this work and substantial $$$ investment the problem is still there, should I be looking at motor mounts ?
The engine/tranny is no where near secure sitting in the existing mounts, have noticed two things that have been this way for quite awhile.
If parking brake is not on when tightening or breaking loose lug nuts car has a lot of rock back and forth and you can see engine moving a lot if hood open.
Last night I put a large screw driver between right side mount where piece from engine goes into frame mount and I can move engine side to side with minimal effort about 1 1/2" or more.
One more thing, when coming to a slow stop at the last downshift just before you stop I get a light clunk from left side somewhere and if you slow down from 50 mph or so to 25 to 30 mph and then put gas back on you get a left side clunk too but not always. Does it sound like bad mounts?

I have been working on my front suspension for last 4 to 5 months and not getting any luck getting rid of the harshness over bumps and the large amount of energy from hitting bumps that transmits back into cabin both from the chassis and steering wheel.
I solved one issue that can be read through on my post for "Bad Engine Mounts ?" but still does not feel solid like it should over bumps. So far this is what I have done.
- New LCA Bushings (solid rubber style rear and Whiteline front)
- Koni FSD Shocks
- VW DG Sport Springs
- 034 Density upper strut mounts
- Meyle HD Sway Bar Link
- ECS Sub Frame Bolt Kit
Had VW Dealer put on rack last week and they could not find any looseness any where in front suspension. In desperation I took LF suspension apart yesterday to see if there was anything that I could figure out that would cause the suspension to not absorb the energy and create this harshness I am feeling.
My first thought is to go back to stock upper strut mounts, there is some give in the OEM mount compared to the 034 Density mount, they are rock solid! The other thing I noticed is the sport spring is rubbing on the strut spring perch.

Then after look at profile of OEM spring on bottom and new sport spring I noticed they are different, OEM is kinda like a hook and sport spring is round.
OEM matches strut spring perch perfectly.

Sport spring is tight
I would consider putting OEM spring back in but really would like to lessen wheel/fender gap and OEM springs look like they have sprung, won't stand up straight on bench cause they are curved after they came out of OEM struts. Also, B6 has no rubber insulators where springs seats into strut, my B5.5 has rubber insulators both top and bottom.

In a nutshell, I'm tired of my incredibly harsh ride. I drive a 2006 3.6L with H&R Sport Springs. I had to put spring boosters in the rear to keep the tire from grinding, but whenever I have a passenger in the back it still grinds, especially over some turns or speed bumps.
The ride quality is also very harsh, it sucks. Plus the front wheels can't align anymore (at least that's what the guy at the mechanic's told me.) Basically, I want my ride quality to improve a lot. I'm debating going back to stock, but I'm not going to like the big gap in between my wheels.

I have a 04 elantra and its driving me up a wall. when driving first thing till the trans warms up it has a harsh shift between 2-3 gears and its rough like all the motor mounts are bad and you dump a clutch. i have tried the tsb reflash and the adaptive learn still did it, Replaced the trans twice reflashed the computer after the last trans and redid the adaptive learn twice fist time at cold temp then redid the learn with the trans at full operating temp.

I have a 2007 Ford Expedition with approx 135k miles with a 5.4. At approx 45 miles per hours it starts shaking and shuttering. It feels almost like you ran over one of those traffic bumps. I've had quite a few issues I've been working so I recently changed all my plugs with motorcraft platinum and all new COPs.
When I am going approx 45 miles per hour it will shutter for about 1-2 seconds with overdrive on. You can almost time it that it will do it every 4 seconds. With overdrive off, you can feel something dragging down the engine and hear a light grinding noise or a mechanical sound but the shuttering is less. I feel there is something definitely cycling approx every 4 seconds.
When i am doing heavy acceleration I feel that it has adequate power and now that I've replace the plugs/cops I don't feel any significant misses etc under hard acceleration (before I changed the plugs/cops I did feel misses).

My 2015 prius series 5 ride is really harsh when gong over bumps! 17 OEM wheels w Toyo tires set at 33 frt/32 rear, Trd springs frt/rear, trd rear sway Cusco frt sway bar, front power brace and center brace! Should go back to stock springs? Or invest in set of soft coil overs ? I like the lowered look too!

I posted earlier about my car idling roughly, the dealership is now saying it may be my engine or transmission mounts. I have a 2002 Passat wagon with 41500 miles.

I have a 2002 echo, and I need some work done on it. I'm pretty sure that my engine mounts are bad, and I know that my front bushings are shot. What should I expect to pay for the bushings/mounts to be replaced? Also, how do I know if my engine mounts are bad? Note that I am a college student living on campus, so doing the bushings will be next to impossible.

I noticed my 3.6L 4Motion is making a hard thump/ticking sound when the car accelerates from stop, and also on turns. I'm going to schedule service for the car next week and I wanted to get a little educated insight. This is strange because I just had two of my cats replaced last week.

2008 GX 470 ... Experience noise that sounds to be coming from the back hatch/toolbox area when going over harsh bumps? If so is there a known fix for this? I was thinking of adding weather stripping in a couple of strategic locations.

So lately I have noticed this shuttering/stuttering when driving. It doesn't happen at any specific time its sort of random. I didn't know if its because of the extreme cold weather we have been having but its been happening too much. But I have also noticed a pretty gross oil smell coming from the car as well. What it could be?

2010 VW Passat - Sedan
See the attached videos. The first one (night time) was made before I took the car to the dealer the first time. Dealer said that I was going too fast over the speed bumps, so I made another video (daytime) showing the speed (10-13 mph). Both times you can hear a squeaking noise coming from the front that I just started hearing last week. The car has only 23,000 miles on it. I bought it brand new back in September of 2010. I don't know what to do because the dealer (of course) says that they checked everything and there is nothing wrong with the car.
What was the cause of it. I can take it to a mechanic and check it myself and then bring it to VW for repairs and telling them exactly what's wrong and why.

I've got a 2006 b6 2.0 with about 92k on it. I bought it Cpo at around 68k 3 years ago this December. My auto tech said I'm going to need a new timing belt in about a month, so once this semester is over in a few weeks I'll be taking it in for that. Anyway, to my questions. My front suspension squeeks quite a bit going over bumps, especially when cold. Is this a sign of bad things to come in the future? Now my brakes, when they get wet they give off a very rough feeling, not very smooth. I have to slam on my brakes to 'wake them up'. Is this telling me they need to be replaced?

I have this front end rattle or clanking. It happens over bumps and cracks in the road. The rattle seems to be more on the passengers side to under the middle of the car. The stats of my Wagon - lowered on Bilstien Sports/H&R springs. All The control arms have been replaced back in 04 and maybe 40k miles ago. Drive axles were replaced once a long time ago, before it was lowered.

I have a 2003 Honda Pilot with 117,947 miles on it. When I reach 40 mph there is a shuttering sound that vibrates through the front floor boards. Took it to a Honda dealer and they could not duplicate the issue. It happened intermittently. Does not appear to be related to outside temperature or level of gas in tank. What the issue may be for the shuttering?

Had drivegear springs installed about 7 months ago or so and recently the front started making a swoosh sound when going over bumps. Took it into the dealership and they told me they tightened some chassis bolts. So I take it home. Problem is still there. So I go back and let them know. I go for a ride along with the manager and he tells me the noise is normal. So now it's not a matter of it being covered under warranty but more of is it a problem at all?
I remember someone telling me it might of been the control arm bushings. I need rubber ones or something. How I should approach this so my car doesn't sound like a 1980's chevy.

I'm getting ready to do some maintenance such as flushing the brake fluid, new air filter, and changing spark plugs. I've noticed lately a noise from what I'm assuming is my front suspension that can be heard when going over small bumps on roads at low speeds. It sound like a squeaky spring, almost like something needs to be oiled. I'm still on stock suspension with close to 80k on the clock, so I was wondering if there is anything in particular I should look for when I'm messing around the wheels bleeding brakes, or if there is a common procedure to lubricate something so the noise stops. I can hear it from inside the cabin so I imagine you can hear it from outside the car.

my P has recently developed a knocking noise coming from the front right when I go over a pothole. My first guess was a worn anti-roll bar drop link, but I've just taken the drop link off and it looks absolutely perfect. (I noticed that they have updated this part since my last 2008 P which had aluminium inserts in the rubber bush and easily distorted - now they have a stainless steel insert.)
It sounds like the "clunk" comes from high up on the front right suspension. I have looked at all the bushes on the arms and they look fine. If this was a "traditional" car I would have guessed that the top suspension mount bearing had failed, but am I right in thinking that the P doesn't have one of these bearing mounts ?

2002 Passat 1.8T 170,000. My motor mounts have been slowly going bad for a few months now and they are now to the point where when I am slowing down as it is shifting down into third, it feels like I am being rear ended. My question is, is this doing damage to my engine and tranny or is it more of an annoyance.

I had my motor mounts replaced about 2 weeks ago with APR ones and noticed that vibrates more than before at idle. is this normal? One guy told me that it takes about a month for the new motor mounts to adjust and then it will not vibrate that much. after two weeks no changes. Also I noticed that they did not put the rubber cover on the left motor mount (passenger side) could this missing rubber cover bring any issues on the short term?
