Hello and Welcome..
My name is ***** ***** Im happy to help / advise..
Is it the centre bearing / bushing you have replaced only?
yes, i only replaced centre bearing.
Okay... when the bearing fails you usually get a banging noise rather than a squeak...as it hits against the outer ring...a squeaking is generally down to the UJ worn/ failing - they are made up of needle roller bearings ( inside the little cups) - they dry out and hence you get the squeak squeak noises... it sounds like you have that issue - it is common.
these are sealed u-joints, so i'm guessing will need to change the whole propshaft then?
It will need either a new joint fitting - or a new shaft. If you undo the shaft and manually move the UJ from side to side - they should "flop" easily from side to the other.. if you have to force it to move or it feels "rough" that's the sign of the above.
Yes they are the sealed ones - but they can be done - they are whats called Staked ones..as opposed to the old type that were helpd with circlips...
You really need to find a garage that has the "kit" for changing the staked type joints - If you can do without the van you can send it away to be done - or , I can give you a contact for that / or exchange shafts... far cheaper than MB new..
i would really appreciate the contact mike, would you know of someone close to me? i'm in orpington , greater london, uk, BR5 4BX
Ah - Im not in your area - but if you do a google search for Propshaft suppliers / repairs in your locale you may come up with one - I would think you would -- the contact I have is HERE... I have used them over the years and I can recommend them..
Are you Kent area?
yes i am in kent
Right - I thought so.. as in Orpington.. it reminded me of another - Kent Tranmissions - they are fairly well known.. just a sec
Ok - they are HERE... that may be a better bet for you.
just one last thing Mike, since i can only hear the noise on the propshaft, but not on the differential, would you agree that this is very unlikely to be a noise being transmited from the differential to the propshaft or do you think a problem with the differential can not be dismissed?
I was going off what you said above - in that you felt there was nothing from the diff... It could be the diff....thats always a possibilty - but again, its usually the joints / one or more, with that squeak sound - the diff is usually a deep drumming noise..like a bad wheel bearing... Again - I would suggest to take it off and move the joints about from side to side to test - again they should be smooth in operation - and no sloppy slack neither in the actual "cups".
That will tell you for sure then that way.
ok Mike, i think i'll take it to the kent workshop as they very close to me and ask them to have a look?
Thank you for your help
