greasing uj's

just greased the uj's on my disco but there is one that will not take any
grease even with a new nipple, it just comes over the edge of the grease
nipple. i am sure the gun is locating correctly, is there a knack to doing
them, all the rest went ok.

Re: greasing uj's

Yes, I have a similar problem. Taking grease but only coming out one side,
so obviously not greasing the whole UJ.

I wondered (but have not tried yet) if greasing after a long drive on a hot
day might help. The problem must be caused by old grease (mixed with dirt)
that blocks things up, higher temperature might soften it?

Anyone tried, or has better ideas?

New Hardy-spicers ? Stuck ones IME have got grease that's gone
completely off, set solid and bollix up the greasing points, of course
you could remove the prop, degrease the UJ, regrease and replace, but a
new joint is only 15 quid.

Greasing is an art form.

Hi,

I chatted to a mechanic at my local LR dealer about this and he suggested
greasing the UJ's after a longish run when they are warmer and the grease is
a bit looser. I haven't got round to trying it myself but it sounds like it
might work.

Cheers

Tony

Usual trick is to warm it up with a hot air gun. (I usually use oxy, but you
need to be careful you don't do any damage)

sometimes it's down to angle and access - can be tight in side the joint and
it may be that yer greasegun is not seating quite true. If the gun grips
properly, it shouldn't leak.

bloody rubber seal has naffed off in mine. you used to be able to buy a new
head end for the pipe, but not any more, in the local shops, buggrem. I'm
damned if I'm going to buy a new gun just to get a new head for the sod.

on one greasgun head/adapter I machine it to a more streamlined shape for
better access to tight spots.

less than that from Paddock.

I tend to keep spare sound bearing sets from failed ones, though. Often
possible to make a temporary repair which gets you back on the road using
"old" bearings.
