View Full Version : Rear end noise

05-24-2007, 07:20 PM
I guess the party is over!! I have been enjoying driving my TR3 then last week my wife noticed a strange noise coming from the rear then I started to pay more attention.. The noise is there all the time but is really noticeable when coasting down hill out of gear with the engine off. At the very least it sounds like bearings the again could be more serious. My problem is that I was following instructions for dismantle but I can not get the hubs off the axles.. Any suggestions would be appreciated

I believe the hubs are held on by the castellated nut and driven by a shaft key.
Once you have the nut off, you may need to use a hefty puller combined with some judicious taps around the edges of the hub with a lead hammer to break the bond.

Are you sure that you don't just have a dragging brake shoe or brake component? Just tryin to save you some grief

If you only need to work on the differential, then don't remove the hubs from the halfshafts. Instead undo the 6 bolts that go through the end of the axle housing (behind the brake backing plate), through the backing plate and into the bearing housing. You'll have to bend back the locking tabs first.

This step is required anyway to pull the diff out, and isn't any easier with the hubs off. With the 6 bolts out, you can pull the hub & halfshaft out as an assembly.

The hubs are mounted to the halfshaft with a "locking" taper (in addition to the key & nut), which tends to get very tight. Using an ordinary hub puller will almost certainly distort and ruin the hub. There is a special factory puller that supports the hub flange better and gives you at least a fighting chance of not ruining the hub. If your local club doesn't have one, and you have to separate the hubs, then my suggestion is to remove the hubs & shafts together (as above) and send them to someone who does have the puller. (Herman van den Akker and John Esposito are two.)

Note that there are other special tools involved in working on a TR3 diff ... might be easier to just find a used one locally.
