i recently replace my tranny mount (3rd time) with a new energy suspension tranny mount, now anything above 60mph there is a very bad viberation! and at 110 seems like the car is gonna fall apart...i know this one is stiffer, but what do i need to do to get rid of this viberation? and also i have a slight clunk when i put it in gear (u-joints possibly)???

what about having it balanced?

i dont wanna have to spend the money right now to get another drive shaft. will a 3rd gen. drive shaft be any different and will it work on my car?..i have an a4.

thanks for the time, and INPUT NEEDED!

Well I experianced alot more vibration in my car also after installing the energy suspention poly mount. I took the preload spacer out from between the mount (i was instructed to do so by someone on this page) and the trans and helped. But you major vibration problem is in your drive spaft. I installed an 88 IROC 1LE aluminum style drive shaft and almost 100% of the vibration is gone now, and i have a T56 so i could feel everything threw my shifter. Try pulling the spacor and see what happens. I hope this helps.

I think a 3rd gen DS will work. 3rd and 4ths arent TOO different underneath. Dont think a new DS is going to help though. Its usually the A4 guys with the bad vibe problems too. My Prothane mount is fine. Can't even tell its poly. Did you use the plate with the mount or no? ES was supposed to have fixed the misalignment issue regarding that but its a commonly reported problem with ES mounts.

 

Its poly, Its a lil harsher, But very much stronger, The viberations are common and an alum driveshaft will help more then you think, It'll be smooth as a caddy after you put one of those in, A 3rd or 4th gen a4/m6 shaft will work.. Just make sure it's alum !

You'll be glad you did it

 

Yeah right I added the LS1 alum driveshaft to my SS and it rides just as rough and my 1LE out of the 91 didn't fit at the rearend the yoke is different.

 

I had the same problem and went to several places for help and finally my local GM center figured it out. When I installed the mount it changed the lateral alignment of the trans. The fix was that we had to loosen up the trans mount bolts and crossmember bolts then push the trans over to the right as far as we could and tightened the bolts back up. Depending upon your situation you may have to go left or right. You might try that and see if it helps.

 

so should i take that little spacer/plate that came with the tranny mount kit out or what? i was thinking about taking an old deisel truck tire and cutting it into a small rectangle, the same size as that little metal plate/spacer and putting it in its place leaving that metal spacer/plate out. what do you think? it would let it move a little more.

i mean the viberation is bad, almost like something is in a bind, when its in drive at a stop light ideling it seem like i have a huge A$% cam in it!

i just did a search on the energy suspension tranny mount, and it said that it is taller than the stock mount...so do you know how much i would need shim down the cross member? could that possible be where my viberation is coming from, something about the angle of the driveshaft or something...but why would it viberat bad just sitting in drive???

steve

 

take that spacer out. its not for our application that should make it better, there will be a little bit more vibration than before but should smooth out at high r's

 

I simply went with an LS1 mount. They are bullet proof and mostly rubber, so last forever, and don't vibrate.

 

If you say that it is viberating bad at Idle while stopped, then I say that you have other problems to worry about. You have probably always had the viberation and it is just showing itself to you because you have a stiffer transmission mount than stock. I will say that I too had the viberation with the ES mount but it went away with me changing my u joints which were bad.

 

I didn't think the u-joint was spinning at idle??

I have the vibration also, and am also running a Comp Engineering poly tranny mount, but don't yet have the money to fix it. It could also be the harmonic balancer. Rarer occassions, it could be a flywheel ro torque converter as well. I will be replacing the mount and swapping an aluminum driveshaft. If that does not kill the vibration, I'll replace the damper. If that doesn't... then I'm out of money, so I hope it does.

Good luck.

 

im going to shim down the crossmember with a piece of thick rubber after i take out the spacer plate from the tranny mount.

but how much should i shim it down? 1/2inch?

steve

p.s. im doing it after the good ol' daytona 500!

 

As soon as I test drove my car after I put in the poly mount, I went on my computer and ordered a stock mount from gmpartsdirect.com. It got rid of all the vibrations, and the poly would make my car rattle at any speed, stop, neutral, on the highway, everywhere. If you dont want your car to rattle apart or to vibrate, get a stock mount...

 

Yes it seems vibration is just part of the deal with the poly mount, mine does it too not real bad but it does vibrate.
It was real bad till I put in a 1LE driveshaft.
