Advice re driveline slack Empty
PostSubject: Advice re driveline slack   Advice re driveline slack Icon_minitimeThu Jan 20, 2011 3:02 pm

Hi, just wondering if theres any knowledgeable folks out there who know the best way to pin down driveline slack. Its been getting worse and now the clunking when going on and off power is getting a bit much. Mostly the front end i think, all Prop uj's are okay. I suspect either cv's, diff or transfer box. Can anyone tell me the easiest way to tell which it is causing the most problem. I assume prop off and jack up front axle and have a play but how do i tell if the transfer box is shafted? Its a D2. Any suggestions? Might change the tranny anyway for one with a centre diff if thats the cause. Cheers Jez

The Clunk on my Disco1 got considerably worse after last years LR christmas do, as the dust caps on the front drive flanges were damaged... Dust got into the grease and sanded down the flange! Easy to detect by jacking the wheel, putting a finger on the drive/flange interface and turning the hub.


Transfer box in neutral, gearbox in neutral, wheels chocked, somewhere quiet. Mole grips on propshaft and wiggle. You can hear each joint clunk in order as you take away the slack. By varying how much you wiggle the propshaft you can start figuring out how much slack is in each area. You can also use a clean screwdriver stuck in the oil fill holes to hold the CVJ or diff, or to help detect movement, if there are two of you.

Windscreen washer pipe as an improvised stethoscope helps, too Smile

Thanks for the tips. I suspect the front diff or cv as its clicking sometimes on full lock. Will try and get a look soon. Was going to try to upgrade to a 4 pin front diff anyway so maybe now is the time to start searching for a cheap diff to build up. Cheers

"Clicking" is CV I believe, but don't quote me!

CVJ causes the clicks on corners, but check the end float first - missing shims could cause noise, wear and slight CVJ mis-position there, and can be replaced without stripping the hub!

Are there shims on the D2 axle?
