Hey,
for starters i drive a st162, 3sge sx celica
Driving home from work tonite i realized the car felt a bit unsettled, like i could feel every bump and vibration in the car.
then, with further driving, when letting off the accelerator and/or braking, a thumping noise occurs! like a constant bump, bump bump, then dissapears when stopped or accelerator is pressed, it sort of eases off.
it seems to be coming from the front, near the firewall. It scares the shit outta me!
Any ideas of what it could be? engine mounts? CV's? driveshafts? Exhaust hiting something?????? is it still drivable lol!
Thanks for the help in advance

the first thing i checked was wheel nuts, and tye pressure. I guess it might be the gearbox then......? does this mean a new gearbox? its already been reconditioned once..........

Engine mounts, maybe. Does it settle once you've been on the brakes a while?

prob engine mount but with out hearing it, it could be a few things! like cv's.have a look at the mounts and see if the rubber looks ok,try and see if you can get some one to rev it,it may not move to the same point as loaded but you might hear it from the engine bay.see if you can physiclly move the engine about or put a jack under the gearbox and slowly push the motor and box up see how far the mounts move! and put the jack on a strong part of the box.or if the gearbox is close to needing an oil change drop the oil out and look for metal.

thanks for the replies.
It does settle when the brakes are aplied but once you give it some gas and let off the throttle, it will knock again. And yes the engine mounts were on there way out, i.e the rubber was cracked on the rear mount. So is this my best bet???
Also the knocking doesnt happen all the time jsut after a little bit of a thrash....
Well im gonna take it to the mechanic, and i will just have to take it on the chin
