About 4 years ago(96,500 miles) I noticed a loud thump thump thumping sound when driving. It was coming from the back of the car (rear axle)

I brought it to my mechanic and he said a bearing was not stilling right and was grinding into the axle. It had made quite a gouge into teh axle. Fortunately he was able to save the axle. He used a repair kit bearing and added 2 quarts of gear lube.

Now at 143,000 miles I hear so noise from the rear axle, but nothing like the thump, thump thumping sound. Not sure if it is a bad bushing or another problem in the rear axle area.

I know the design of the rear axle on the Marauder, Crown Vic ans Grand Marquis all suffered this problem. It is a rather poor design that started in the 70's and was never given an easy fix by Ford.

Has anyone else experienced this problem? If so did you just get a entirely new axle and better bearings? I plan to keep the old Marauder for as long as possible. So even if the repair is costly, it should be worth doing.

I'm surprised that the repair bearing lasted that long. You should replace the axle shafts and use stock type bearings.

I've got a set of 28 spline axles in excellent condition if you need them

Thank you for the information. An axle shaft. I assume I need 2 of them. They run about $85.00 each. So I may not have to replace the entire axle, just get a pair of axle shafts? Plus new bearings

Yes I may want to purchase those spine axles
