Warning! This is a potentially difficult job. Many people don't bother and get a garage to do things for them. I did the job myself. It took four hours for one side and five for the other. Reading the description below does not give any idea of the amount of effort and patience required. Freeing up and driving out firmly lodged parts can take a long time. Both times that I've done this job I've been alright....just. |
Firstly the suspension strut was removed from the vehicle.
The picture shows the strut firmly held in a vice with the wheel bearing visible. The bearing is held
in by friction with a circlip either side for added security. The bearing is held
on the hub by friction also.

The centre hub was removed using two methods. Firstly a punch was used to hammer it outwards. Since this started to mess up the surface, the method in the Haynes manual was used. Here the wheel bolts are threaded into their holes in the hub and pushed down onto packing pieces. Sockets will do. This causes the hub to pulled out. It can take a fair while to do this. As it progresses out the bearings will most likely fall apart leaving just the other race in the strut. |
The outer race was removed next. Firstly everything was softened up by heating for 20 minutes with a blow torch. The differential expansion as parts are heated helps flex the surface contact and make driving/pushing the bearing out more easy.
The assembly was then placed in a vice and the bearing races pushed out with the aid of carefully placed packing pieces (sockets will do).Using a vice and packing pieces means that the strut, the bearing and the packing pieces need to be placed and the vice done up. This might take ten minutes to get right. It's quite tricky doing up the vice with your knee whilst trying to hold the parts. Having two people would make the job much easier.The force required to get the bearings in or out has been within the capabilities of the vice. Due to the nature of tolerances some will be easier than others. I've done this job twice and the second time it didn't take too much effort but the first time I was almost at the heave limit. |

I made a mistake once when I forgot to reattatch the brake crud guard before pressing in the hub. It wouldn't fit afterwards because the hole cut in it was smaller than the outside diameter of the hub. The solution was to hacksaw a cut line in the gaurd and then use its flexibility to allow it to be pulled over the hub. |
The circlip was then replaced. Finally the strut was refitted to the vehicle. |
