UJ's, sorry longish post

(1/5) > >>

Snooky:
Went out and got some new UJ's ready to replace all but one that was done not too long ago.
Went to a mates house to fit, more tools etc, and a bench vice, one of the things you really do need...
Proceeded to remove the old one from the rear propshaft, not real problems, although to be honest we should have agreed to leave as it seemed OK, but I just wanted new to be sure....
Anyway, proceeded to fit the new ones, compressed the bearing housing with the vice then added the "old socket" to run it home, and needed to add an extentsion to the vice to home the thing in, big pop/bang and it was home, but took with it some of the casting, nice sharp finger slicing kind  :? , then did other side same effect, and the UJ was not as free as I'd have thought, with no grease etc.
did the other side of the shaft, exactly the same, big pop/bang and in with the addition of more metal slivers, but hardly any movement on the UJ, not at all happy, but fitted and tested, loads of vibration, took it off to find both bearing housings on one axis cracked, which they were not when first fitted.  :evil:

So, what do you think, cheap dodgy UJ's or something we done wrong, even though it was text book fitting as per manual, and the same as we have done before, and we are not stupid when it comes to engineering.
Even took 2 of the old bearing housings and fitted with easy compared to these ones.
So we recon the housing is too big for the casting on the shaft and in fitting it compresses the bearings onto the UJ too tight, could see where they had been seatedfrom the scratch marls on the machined face.
Will be off to the local dealer tomorrow to get some I know will fit fine.

Anyone else had this problem?
Where do you buy your UJ's from?

TDi90:
well where did you get your UJ's from.
speak to paul at challenger 4x4 just up the road from you, and have a chat with him about it, im sure he can sort you out with some, and explain what went wrong/tell you how to do it.

Snooky:
They came from a so called Land rover expert with years of experience, even fitted my last one after I asked about a rumbling noise, although he fitted different ones to the ones he sold me  :o

Challenger isn't that close to where I work, but the Dealer in Basingstoke will be tomorrow, guess there won't be much difference in price for ones I know will last  :?

rollazuki:
You guys got the correct size UJ spider?

Theres a slightly longer version that can cause all kinds of problem if you try to install it in the smaller size propshaft.

Cant remember the size(Im sure the anoraks will arrive in a bit with the dimensions) but its a gnats hair off , and WONT go in.

Snooky:
These were the right length, I know the ones you mean, another supplier did send my mate the wrong ones and we tried to fit them, only when we got the vernier out did we find the reason they wouldn't fit.
These seemed to be too thick on the bearing housing if that makes sense?

The loud pop as it dropped through normally happened with a puff of smoke as it stripped a sliver from the housing... :shock:
