recently bought a 91 galant vr4 that had a new clutch installed. All i had to do was put the gearbox in, simple.
Gearbox in everything is fine, except there is a whining/ grinding sound coming from the front of the car.
the centre support bearing on the driveshaft needs replacing but it sounds like its come from the front of car.
- increases with road speed
- coming from front
- can get rid of it by driving and slightly backing off.
- occurs in all gears even with clutch engaged
i reckon its the input shaft bearing (or a main bearing in the gearbox)
or possibly bearings the transfer case. could also be the center support bearing for the driveshaft but it doesnt sound like its coming from there (maybe sound echoing??).
going to drain the gearbox oil tomorrow to see if there are any shavings.
Thanks for reading, any help is appreciated. Still new to vr4s. thanks for the help!
