So a bit of a wurring sound as started and it gets bad at highway speeds, had a look at the rear wheels and there is a bit of play in both sides. Has anyone changed the bearings on there car before and do I really need to get hold of special tools to do?

I did this recently. You need no special tools aside from an impact wrench to get the suspension apart, but you need to take the bearing carrier to a shop to have these bad boys pressed out and new ones in. Prepare to be without your car for two days depending how much time you can dedicate and how soon the machine shop can squeeze you in.

Thants for the advice, no chance of getting them out with a slide hammer then ?

not likely, and then putting the new bearings in without damaging them would also be a trick. it cost me 60 bucks to have it done right and now I don't have to worry about it. that is cheap piece of mind for a car of this quality.

Thanks for the help, I have the equipment at college luckily so should not cost me anything just got to find the time to get the assembly off !

It's really not that bad, just keep track of all the bolts

The machine shop presses the old bearing out and presses the new bearing in. If you have access to a hydraulic press as school, you're good to go. All you need additionally is some scrap rings or other metal sundries to back up the assembly, which will give the clearance needed to pop the bearing out.

When pressing the bearing in, all you have to know is that the setup must be such that you aren't pressing through the rolling elements. i.e., if the outer ring is press-fit into the bore, then you must press on the outer ring to seat it, not on the inner ring. Most bearing failures occur from improper assembly. I'm not familiar with the rear bearing, but I do work in the bearing industry.
