HI

My 1975 TC 1500 rear axle bearings doesn't sound too healthy ( Spun with both hubs removed to change to MGTF studs)

Question is, should I rebuild it myself, or as a don't have a press should I get someone else to rebuild it, or find a good second hand unit?

Regards

Barry

On the 1500TC, you can remove the differential from the axle case easily and without any special tools. reasonable condition 2nd hand diffs for these are fairly easy to source and much cheaper (usually) than recons. You can even take the opportunity to upgrade from the 3.89 ratio you have to the later, taller and stronger 3.63 (though you'll need to change the speedo driven gear as well to correct the speedo reading)

As noted elsewhere by me, you can even use a 1500 Spitfire diff by unbolting and scrapping the rear case and stub shafts and cutting off the front mount with a grinder. which broadens your choices considerably. I think the 3.63 can also be found in Marinas and 1500 Midgets. And of course later 1500HL Dollies!

A complete axle swap would be the easiest way if you can source one with a known good diff. The last axle swap I did took me 4 hours from start to finish. It would also be the perfect opportunity to rebush the rear suspension.

Yeah but you can swap a diff in an hour! Single handed! And it's a perfect opportunity to change the axle oil!

Thanks for the replies

On second look, I think its mostly the bearings, do I need any special tools to change them?

Do you mean the rear wheel bearings in the end of the axle case? If so - and you have already removed the hubs - then you have already done the hardest bit of the job! Simply undo and remove the 4 bolts through the brake backplate and jury rig some sort of slide hammer on the end of the shaft and drag the whole half shaft out. measure and mark the position of the bearing on the shaft, then simply press (or bash) the old beaing off the shaft and gently tap the new one into position. Reassemble in reverse order as the books always say!

The wheel with loosened wheel nuts make a great half shaft puller.

As I don't have a slide hammer I will give it a bash tonight!
