Thread: Front prop shaft noise??

I have had the gearbox, transfer box and both front and rear diffs reconditioned. I also bought new aftermarket prop shafts front and rear and fitted these. The noise is still there.

The latest advice I have says the front propshaft is in phase and should be 18 degrees out of phase. When I speak to Land Rover they say the original front propshaft is 45 degrees out of phase. Someone has mentioned I need to put a series 2 propshaft in with some sort of conversion which will cost $1,000 because the vehicle is lifted.

Please help I have no idea what the real cure is.

Yep, OE front shaft needs to be run out of phase as the diff pinion is angled up at the t/case, or you need a DC at the t/case end (and it won't cost $1000)

I'll dig the relevant links up.
Sorry about the picture size, the site has re-sized it, I'll post a bigger one later.

As Roger stated earlier,remove the front shaft and take the vehicle for a drive to see if the noise is still present?? If it is gone,then you need to worry about driveshaft phase etc.But if it is still there,then you will need to start looking elsewhere.Check the simple things first.
