Thread: Drivetrain Backlash

I have a Disco V8i S1 1998. I had new suspension put in 3.5yrs ago which I think gave me a bit of a lift maybe 30-50mm I think this might be the instigator of my problem. It drove great after putting it in but I am having a problem now which 3 different mech shops can't put their finger on. I am getting a backlash somewhere in the drivetrain. It is random & unpredictable, can happen at any speed going straight or turning. I describe it as a gadoonk gadoonk cause thats what it sounds like & it happens as a pair of knocks. So far my process of elimination has involved checking all uni joints all are Ok. Removing front shaft & driving it locked it remained. Removing rear shaft driving it locked it didn't happen but I can't be sure it wouldn't have I only drove it about 20Ks & I have had periods where I have driven it for over 100Ks without it happening. I have checked the hand brake & had it adjusted all looked Ok. Drained transfer case & inspected all looks Ok no metal fragments signs of ware or excess play. Checked rear diff for metal fragments & signs of ware all was Ok. Last thing my mech said the next thing he would look at would be the half shafts. I have spent around $500 now investigating I cant keep going on like this. Im hoping somebody knows what is causing this. Help please.

They will all have a bit of backlash in the drive train because of the constant FWD.You can find a little bit in everything from the drive plates on the axles in.
