This is a copy of a thread I have started in the suspension and handling section of the forum, as I'm having no success there I'm hoping sticking it up in here would help:
I need to replace the front wheel bearings on my father-in-laws 1999 XJ8. This weekend I did a bit of investigating and got as far as removing one of the brake discs (not easy!). Anywho, on the rear is a castellated nut which appears to be held in place with two small pins on a flexible metal tab. I'm thinking a punch and a gentle tap will remove them.
My question is, is the castellated nut a left or right hand thread, and what can I use to remove it?.
Also it would appear there is a correct way of refitting this nut once the new bearing is in, but I can't find out what that procedure is.
I'm hoping to remove the bearing from the hub whilst it's still on the car using a bearing puller/pusher. It's the 80mm version. If that's not possible, I do have a vice, but I don't want to go down the route of bashing the new bearing in.
One more query, does it matter which way the new bearing goes in?.
Any hints/tips would be greatly appreciated.
