Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Roadster 3.7 - Rear axle

Hello,
I have found the following. On the rear axle, when you move the wheel axially back and forth you notice a gap of a few millimeters. Is the problem the wheel bearing, or the rear axle? If so, can it be adjusted?
Thanks for your comments and Merry Christmas

Check the U bolt nuts are tight On some cars they have habit of loosening

You do not say exactly where the “gap” is.
Bear in mind, when you move the wheel axially, there will always be some “slop” or backlash in the differential gears. This is essential to ensure clearance as the gears heat up and expand. It is usually set by applying shims to the gear mechanism. Unless it is giving a problem, I would leave well alone.

It feels like the play is in the wheel bearing. The wheel can be clearly moved back and forth. Loose U-bolts are not the cause though

Both sides or one side only?

It sounds like you're describing end float in the diff, there should be some. How many miles has the car done ?

Logic would suggest that if you grip the wheel by the tyre and rock it left/right or top/bottom and there's play, then it's the bearing .... if you pull the wheel in and out evenly and there's play then it's end float in the diff (tho if the bearing is really slack you'll feel both)

The car has 32000km. On the left side it is more, right less.
I can pull the wheel in and out, so it can be the end float of the diff. How this can be solved?

As long as it pulls in and out without excessive 'rocking' then it does sound like diff end float .... someone more knowledgeable than me will tell you if the amount you have is more than normal.
