Occasionally when I come to a complete stop I will hear a loud clunk in the back of my car from underneath. About a year ago I put on brand new rear shocks and 6 months ago brand new rear coils. Does anyone know what it could be?

Thanks,

did you hear the sound before the shocks or spring replacement?

did you make sure the spring is well seated?
How are you bushing?

Wait for the experts to get on.

 

sounds like my (86) 740 i was told it was the transmission!!!

 

ya, i am wondering if it is the transmission(auto). my transmission does make a loud noise when i am at this stop light on a steep hill when i take off.

 

Try coming to a stop in drive, then coming to a stop, coasting in neutral.
This will take engine torque out of teh equation.

Regards, Andrew.

 

MY 2005 s60r , auto trans clunks in the rear when I stop but it won't do it if I stop while car is in neutral
. does that mean my eng torque mount is bad?

 

an S60 has its own forum, thats a *completely* different car than the 240/740/940 family of RWD 4 cylinder cars from the 1980s/90s.

 

thanks , new at this

 

IF this car is AWD/4x4, rear end clunks are usually the differential mounts or U or CV joints on the half shafts and/or main drive shaft. if its a FWD car, rear end clunks are pretty uncommon, other than from worn out suspension bushings (and those would be more likely to clunk from braking than from engine deceleration in gear)

engine mounts on FWD cars generally result in FRONT end clunks/clanks (and excess engine movement when observed while blipping the throttle with the hood up).
