getting a thump when i accerate hard...checked transmount several times...its perfect any ideas????

 

Torque arm?

 

Yeah, try the torque arm. Also look at the lower control arm bushings. My Iroc had a bad control arm bushing and did the same thing. Maybe a motor mount. Hope nuthin majors broke.

 

loose swar bar where it mounts to the axle ...if its loose it will rotate a little and made a popping noise because of the friction

 

I know you said its not the tranny mount but are you sure??... If your running a stock mount it compresses over time and will appear to look fine but when you floor the car it streach out severly and let the tranny stop hit the tunnel. It will not break the mount on alot of M6 cars since we have the little bumb stop on the top of our trannys.
I only suggest this because I just went thought it. It was fine untill I put on Drag radials and stressed it to the max and then came the big BANG.

Did you take out the trans mount and visually inspect it?

I have had this quite a few times, it was always either a broken trans mount or broken torque arm.

 

How much is a broken torque arm?? and will you lose performance b/c of it?

 

mount looks perfect...how do you know you have a bad torque arm? besides it looking physical broke or bent?

 

i had a bold that connected the torque arm come off wich made it swat and hit the metal around it when i accelerated, to see if you got the same problem get under your car and try to push it too see if it will move. if it does then a bolt is probobly loose somewhere.

 

still have the problem...torque arm is fine...transmount is fine... anybody please! on on hard acceleration...

 

What about the torque arm bushing? On the tailshaft of the tranny.

 

u joints?

 

brand new energy suspension torque arm mount....checked it out it looks fine....

put new drive shaft 1le with new ujoints about 6months ago....

 

exhaust is super tight...its definatly not hitting.... anyone think it could be relocation brackets on a non lowered car?
