There are now aftermarket front diff bushes available from Nolathane Part #49197, and if you or your mechanic is keen, they are able to be fitted without removing the diff or suspending the engine. Simply unbolt the front diff and slide it sideways away from the mounts, carefully cut away the rubber and the steel original bush "shell" and follow the instructions for fitting the new bushes. The new Nolathane bushes are in two halves with a steel tube insert and can be slid into position then tightened up securely. It has been done on the ground with the vehicle securely supported on stands, with the LHF wheel off and caliper removed and tied up out of the way, but would be much easier on a hoist. Remember to orientate the new bushes correctly as per the instructions and you're away. So far, there has been little feedback if there is any massive diffference in NVH, but anything would be better than flogged out original bushes upsetting front drive shaft pinion angles etc. So, this method allows for a more cost effective way of fixing the weak factory bushings without huge cost involved. Hopes this helps.And always, if you are unsure, get a quote from your mechanic and be safe. Should still be heaps cheaper than it used to be.
