So here's my dilemma. I recently purchased a used evo 8 40,000 miles. Few weeks later rear diff locks up. Now months later I replaced the rear diff, upgraded to a Shep stage 2 t-case, replaced the output shaft, cv axle, Abs module, and ACD pump. The whole time the cars been at the dealership running into numerous problems. ACD issue is now fixed, see ya later 3 lights of death. My new problem is I test drove my car today and it shakes violently in all gears at all speeds. I am a new evo owner and I love this car, just wish I could get it back to its normal self. Any advice or help on this major problem I'm having will be extremely helpful. Thanks in advance.

 

Engine runs smooth as silk? Neutral for instance.

 

Sounds like something didn't go back together quiet right. Get it up on jack stand and spin the wheels/axles and such to make sure nothing is binding up

 

check motor mounts

 

Cv axles. To replace the rear diff and trans case, all of them have been touched, so..... Could be any of them.

 

Yeah I called them this morning and told them to check those first.

 

Problem solved the drive shaft was missing a nut and the other to weren't even tightened. Ridiculous!

 

wow, dealerships for ya! you should make a big deal about it

 

i got my car back from the body shop.... they dropped my entire rear subframe to repair a damaged frame rail after being rear ended... my ds bolts were all hand tight at best and it only shook when above 80mph decelerating... it did clunk on gear engagement but i assumed it was the recently installed solid diff mounts... glad you figured it out...

 

Sorry for thread hijacking, need help in solving driveshaft play! There is alot of play, replaced the two driveshaft carrier rubber bearings & also have the torque solution bushings fitted...

 

Yeah I did!
