Default Front Wheel Bearing

Hey guys. Well looks like another S80 project. Looks like it's most likely a bad wheel bearing. My understanding is the replacement part is "wheel hub assembly".

- Has anyone replaced a front wheel bearing on a 2008 S80 (or similar vintage)?
- Is this something a DIY person can do?
- Any special tools required?
- Any watch-outs?

I've been doing my own auto repair stuff for quite some time...so my skill level is pretty good & have a good selection of tools. Wanted to get some opinions before I order parts...and dive in.

Thanks

The brakes need to be removed to get access to the steering knuckle.

The basic procedure is to remove the strut from the steering knuckle. Unbolt the ABS wire. In our shop, we also disconnect the tie rod at the knuckle. We've also been undoing the lower ball joint to get the knuckle off the car.

Once you have everything away from the steering knuckle, you need to unbolt the end bolt on the drive axle and push the drive axle through the bearing. Now remove the steering knuckle and bearing.

With the knuckle on the bench, remove the bolts on the rear that hold the bearing on the knuckle. Depending upon what part of the country you are in, you might have this thing frozen to the knuckle from rust. Here in Alabama everything comes apart like you are in heaven since no rust here.

Clean up the edge of the knuckle and install the new bearing.

Hey Tony thanks for the detailed info.

A few questions:

1. Just to verify. You saying the wheel bearing hub assembly does not need to be pressed out & the new bearing assy pressed in? That it just needs to be unbolted on the back from the steering knuckle & removed (assuming the bearing assy is not frozen)?

2. Is there any chance the bearing assy can be removed from the steering knuckle while still on the car...without disconnecting the tie rod and the lower ball joint? I know that this may sound like a silly question if it's actually physically impossible...but I haven't gotten in their yet to see things. And of course there's the CV joint drive shaft as well. I don't mind the extra disassembly hassle if it is possible.

3. If the tie rod end & lower ball joint are disconnected...will this result in the car needing a front end alignment after reassembled?

Thanks again!
