Knocking from diff

Recommended Posts

Hey guys, after a wheel bearing failed in a major way last month I've started having a look at the rear drivetrain. With the car up on axle stands rotating the wheels results in a noticable click/knock from the diff. it happens about every 1/2 turn of the driveshaft. It's not noisy and cannot be heard when driving however the click can be felt through the rear wheel when rotating it.

 

With the driveshaft locked up and just rotating the wheels the same click is present.

 

I'm guessing it shouldn't do this, but are there any pointers as to what it could be? I'm tempted to just replace the diff anyway as the open one sucks.

it could be the drive shaft cv joints, i have had this on a front wheel drive car where the balls in the cv joint had worn a groove in the housing, it then made a clicking noise when driving and turning the steering wheel.

 

what it could be on your car, the joints have worn in its normal position (on the ground), now that you have jacked up the car the drive shafts will be at angle if you see what i mean, and the ball/s jumping in and out of a groove?

 

could be worth a check? lets us know what you find.

 

regards chris
