Replacing UJs

[Bob696]

Rear UJ on the rear propshaft has gone.

Droped the propshaft out

Get the old UJ out and notice it dosnt have a grease nipple and has never had one :?:  It is shot to [!Expletive Deleted!].

Get the first bit of the spider in (into the coupling flange) but the 2nd set just wont go in. I managed to break a 1 ton vice trying to get it to fit. Am I missing something here? Thought this was supposed to be an easy job :!:

Are they held in with clips or a pinch nick on the ends

[Bob696]

got the old UJ out with little trouble ..removed circlips ..used a drift ets.

2nd pair of the pin bearing housing just wont go on. 1st pair was a struggle but they went in eventualy.

[hobbit]

From what i've seen I think they are not tapered, did you inspect the yokes for any damage, or dents?

[Bob696]

yup ...no apparent damage .. only thing I can think of is that they are the wrong UJs :-(

Its got me beat

It could be, I've heard of dual size uj's, but didn't think they would be fitted on these things though, like I say most of my work is with series ones and trucks, somebody know if this is so on the defenders?

there is different types of joints but i dnt think the sizes are different,from what youve said it soinds like uve droped 1 of the rollers in the cup & as uve tryed to push the cups together its jammed it & uv probably just made the joint scrap :oops: its hard to explain by posting as ive done so many i can practically do it with my eyes shut although i still manage to knack the ocasional 1

True, its best to slap as much grease in the rollers as poss to help hold them from falling over, its a balance of tapping a beingas careful as you can not to drop the needle bearings out

[Bob696]

well after screwing up 1 UJ and probably another (good job paddocks have them on off at 4 for 3) I gave up and took the prop shaft to a garage (wimps are us, thats me)

Cheers for the help guys

only do that if youve taken the grease nipple out as otherwise it explodes if u squeeze it in the vice  :shock:  or doesnt go back together

There are a couple of different sizes, but they are different in the distance across the flats rather than in the diameter of the shells.

Aside from the problem of dropping a pin, you can also get them very stuck if they don't go in square.   Especially on a vice, as you push them in, the yoke has a tendency to twist a little, so the cap tries to go in at a slight angle and sticks.

Bob,
 
get yourself another set to 'keep on the shelf' as those from Paddocks dont seem to last very long - mine didnt - got the proper GKN ones and they have been much better.
