I think my propshaft bearing is on its way out, as there is vibration at 40-50mph, but then it goes above that speed.

What are they to fit? do you need to have a press to fit them or is there another DIY way?

If its drivetrain related you should feel the vibration through the car itself (like the seat and floor) rather than through the steering wheel.

 

You can normally tell if its the bearing before you remove it, the propshaft will be sagging in the middle of the bearing and it might be torn.

 

If its not the bearing it could be the Rear gearbox mount, its worth changing wether or not the prop bearing is damaged as its often the sagging of the rear gearbox mount that damages the prop bearing.

 

Notchy Prop UJ's are another possible culprit , as well as the actual diff itself (although very rare, and usually noisy too)

 

No need to press fit them, not that sort of bearing. Might need to knock the old one off with a vice and hammer if its stuck but thats it.

 

Drop Exhaust.

Remove heatshield (if it still there)

Mark the two halves of the prop with a white market/tipex so you know which way they should line up again afterwards.

Undo the 4 17mm holding the Two prop halfs together

Undo the 2 17mm Bolts holding propshaft to the car

Pull the front end of prop out of gearbox

Undo large nut on end of prop

Pull of Bearing

Slip new bearing on

and put it all back together

 

Make sure you put the spacers back in the same way they came out where the bearing carrier mounts to the car, and that you line the two halves of the prop back up together in same place.

Mike,

 

I replaced my prop bearing with a good used one off j1mmytt on Sunday. However, I am still getting vibration at 40+ mph. It has been suggested that I replace the gearbox mount. But I notice in your reply here to Sussex stu that "Notchy Prop UJ's are another possible culprit " When I had my prop out the UJ was notchy, is there any way to 'free up' the nothcyness (SP LOL) on the UJ ?

Notchy propshaft u/j's will give a vibration.

Any way to cure it or is it replace time ? :rant:

Replacement time unfortunately:confused: Could try and get new u/j bearings! I am not sure if mike feeny can get hold of replacement u/j bearings or whether you have to buy a whole u/j kit??

 

I have seen Z32 propshafts with new u/j's so it can be done :)

Some u/j's have grease nipples which would be helpfull :)
