My son 22 years in the trade has done the work, problem started with light whine 20k up similar to wheel bearing, started investigation, rear diff checked and overhauled at Likes Landover renewed bearing, front transfer box clicking noise nose bearing not good replaced Transfer box recon from John Craddock, Haldex stripped and serviced, reassembled, problem is we did not test front transfer box and rear diff independently both changed together. Problem now is clunk believe from rear end when going forward slow then into reverse as if there is play in transmission not there before, Or when driving along at constant speed taking foot on and off throttle feel the play in transmission. play is not there when Haldex is disconne
 
The prop shaft on my 2010 td4e had a little rotational play, before I removed it completely. (the back wheels were scrabbling while driving around a tight circle) Haldex clutch seized?

I originally thought the 2 piece prop - shaft had developed play/damage at the centre bearing sliding element, caused by wind up from the diff/Haldex, but its only a degree or 2 of play over its length, possibly enough to cause a clunk?, I couldn't hear anything over the sound of the front wheel bearings giving out at the time.

The IRD output flange is much more at 10 - 15 degrees of slap..., now the front wheel bearings have been replaced, and the propshaft removed. Front end seems quiet, the rear end faintly drones ..but yet to properly diagnose the fault .Diff nose bearing giving out probably ?
 
The rear diff should be silent, so noise indicates a failing pinion tail bearing.

Play in the PTU suggests the splines to the gearbox are worn, which is a common problem. I believe that LR were a bit to sparing on the assembly line with the anti-wear grease, which causes the splines to fret and wear.

Appreciate the reply Nodge. That's the bearing for the shaft directly connected to the Haldex unit?

That's the one, although once the tail bearing case hardening comes away, the bits travel through the pinion none bearing, destroying that too. A kit is available with both bearings, crash tube, oil seal and special nut. However you'd need the special tools to carry out the rebuild, which adds about £120 to the price.
Getting a reconditioned unit from Bell Engineering is the best bet, although not the cheapest option.
 
I need the car as a daily driver and thought about dropping the diff/haldex/& rear drive shafts from the car. Thinking the car would still be drivable, then refurb the diff and Haldex. In terms of special tools, can they be made?
 
Unfortunately the vehicle can't be driven with the diff removed, as there's nothing to support the drive shafts, which remain connected to the hubs.
