Changing 944 rear wheel bearings

Hi

Has anyone changed the rear wheel bearing in their 944 alloy arms, just looking for tips.

Hello
you will need a press to do the job right (without damaging other component with hammering). Is a tight fit -in most cases the old bearing is destroyed- so attention is needed for the new one, hope it helps a little

Hi

Pressed the bearings out OK, the inner-outer race gets stuck on the drive flange ruining the bearing & seal. On the Pelican 944 forum they said to freeze the bearing and heat the arm when fiting the bearing.

When I did mine I heated the arm up in the oven to about 100°C the bearing droped straight in, you will need to have press handy as the socond one I did just treid to nip as the bearing bottomed out, but the hardest job was removing the old ones.

Talking

Just found out from a farmer friend that if you run a bead with the welder around the outer race of the bearing when its in the housing, it will shrink the outer race. It will come out quite easily. I tried it tonight, ran a bead just on the wheel side of the race the first time. It took a little work to get the bearing out. Second time I ran a bead on both the inner and outer. Then I had a 2.5" piece of pipe that I ran a bead around with the welder to make a bearing driver and it was just big enough to drive that bearing out with a couple whacks.

I have this down to a fine art. We have a 10,000kgf press and access to a 100t, this is a better method sometimes when the part is awkward or lacking in meat to press against, like T1 and T2 balljoint cups for example. 1 slow bead with a MIG and leave it to cool for 5-10 minutes. 1 blow with a hammer isn't unusual. The amount of shrinkage can be impressive.

UK readers note 'signs of excessive heat being applied to suspension or steering components' is an MOT faliure.

The hard part I found was getting the wheel hub off so I could get the bearing out. I had to remove the snap ring and press the bearing out with the hub still on. Then the hub came off easier.
