awd prop problem

cluckmaster · Jul 19th, 2012, 09:06

I have fitted a second hand transfer box on my 98 awd, but when i put the the prop on the back end of the car feels like it is jumping off the the ground at speeds of over 25mph. It never did this before the transfer box self destructed, any ideas?.

Are all four tyres the same make and size, also make sure the tread depth on all four tyres are very similar, the closer matched the better - Mike

Is the viscous coupling ok and new transfer box is it the same part number as you took off

I have checked tyres no problems there. I had to change the end on the transfer box for my old one because the bolt hole spaces where not the same, which then let me fit the prop. I was thinking maybe balancing, the prop was rebuilt less than 10,000 miles ago.

really silly question the two bolts that hold the centre bearing onto the car are actually tight

I had a problem much like yours.... got it re-balanced and it has been perfect...

Finally got round to sorting the problem, turns out the flange on transfer box is wrapped. thanks for everybodys help.
