Front UJ Replacement

Greetings all.....

Vehicle vibrating badly under load. Tracked problem to UJ's on Front Drive Shaft.

Going to remove the shaft and get a specialist drive shaft service guys to replace the UJ's. Plan being to drive on rear shaft in the interim.

Is there anything else that I should be weary of when removing the front shaft - any seals or anything that should be changed also? I have visions of unbolting the shaft & the diff oil spewing out all over the place......

Any advice appreciated.

Thanks

Niall,
You are fine to taki it out yourself, you should not encounter
any problems, it is just a shaft. You may have to compress the spline
a bit to get it to clear.

Hi Niall,
The bolts tend to be bloody tight and at the same time difficult to get
to, but apart from that you should be fine.
I assume that you have the centre diff lock switch so that you can lock
the centre diff - if you don't you won't be going anywhere once you
have removed the propshaft!
Why not change the UJ's yourself - it's not rocket science - all you
need is a vice (although a luxury) and a big hammer ;-)

Thanks Julian.

Will be happy to get the shaft off myself. For lesson 2 I'll be teaching myself how to get the new UJ's fitted and am saving that for later.

It's fulltime 4 wheel drive - so will I still need to engage the centre diff to get her going?

It's currently sending power to both axels. If front shaft is removed, should still have power to rear shaft & wheels....???

Thanks

Hi Niall,
Yes, if you don't the output to the front wheels (which will not be
attached to anything) will just spin round.
By locking the centre diff you ensure drive does to the rear wheels as
well.
You need a centre diff lock switch to be able to do this, otherwise the
centre diff lock will only lock in Low Range which will be a bit slow
for day to day driving.

I was of the opinion that u can set some wire underneath (or unplug) that simulates having CDL pushing in (when u don;t have it)
Its a hack but might be useful.
Can't find that link/note right now so I might be talking off the side of my head (again!)
Better getting the CDL and putting that in (its a no brainer install)

Thanks Brendan

Have the magic button.

Going to check that the oil in the diff - make sure it's up for a bit of trucking.

Cheers
