P38A Juddering / squeaking

Gazza36 · Apr 9, 2019

Hi all, we have developed a new problem whereby there is a bad juddering accompanied by a squeaking sound which sounds almost like a fan belt but is movement related not engine related, the noise stops under power but returns when you take your foot off. I have some thoughts, I you guys have some ideas, many thanks.

Manual or Auto?
Binding brake? UJ failed?? VCU seized???

Auto, I need to get some more axle stands so I can get all the wheels off the ground to investigate further. The front prop seal on the transfer box has leaked a bit but all the fluids have been changed recently.

You sure that there is still oil in the transfer box?

Also noticed there was a lot of play in the UJ going into the front of the transfer box, don't know if that is relevant?

Aha, one obvious problem.
I would fix that and move on from there. Play is never a good thing.
The reason I ask is my 1999 has a fit if lifted off all four wheels and put into drive. The traction control goes ballistic and tries to control everything.
I would have suggested putting it into drive while all four in the air to listen or inspect but that isn't going to happen being a 2000..
I'd start with the obvious propshaft and see what happens.

Buggered UJ would get my Money.

reinforced by the fact you can feel one is loose

Fix that UJ before it breaks and slaps the side of the gearbox.

Gazza36 · Apr 11, 2019

Will do, many thanks.

Gazza36 · Apr 11, 2019

Many thanks, can you drive it with the prop removed?

Mark Piercy · Apr 11, 2019

I personally wouldn't.

Yes, for a short time but take it easy.

It might knacker the viscous coupling.
