Outer Limits 4x4 Board

got a swb with 3in susp and 2in body. When deacclerrating from coming off the trottle i get a grinding noice and vibration in the diff area in rear but goes if you acclerrate again.
Could it be uni's?
its a mild noice like a drone.
any ideas guys?

Driveshaft vibes from the lift? I'd grease the uni's and see if that improves it

Also check the slip joint in the tailshaft. I have to grease mine regularly because it has a bit of play, otherwise I get this noise as I come off the accelerator.

Maybe the bloke who did your lift was gunna put drop boxes on and the poor bugger's stuck under there with grinder in hand

ha ha maybe hes still there lol na iv got drop boxes but il try the grease uni ect and see how it goes.
mine sounds the same as yours zerko, off throttle and it appears,back on accelerater and no noise.
il get back to you all.
thanks for help.

We have a LWB and it does the same thing, only ever noticed it when we where on the beach in FWD. We have been through the process of checking everything that has been mentioned, and yet we cant find anything wrong.

We even wentas far as buying a new shaft, new uni's and had them put in, bu guess what the noise was still there.

So, now we just put up with it.

How'd you go with this? Have you got it sorted? Interested to know because I have the same problem

We had a similar problem and someone suggested to put thicker oil in the rear diff. It is still LSD oil but we put in 90 grade and it seemed to get rid of the noise.
