Default Wheel bearing replacement. How difficult?

My wheel bearing is crapping out on me? How hard are these to replace and are there suggested replacements while I'm in there?

Also my abs light is on. It went off for awhile but came back on. Ideas?

Rear wheel bearings require a press. Replace both at the same time.

What I did: ordered OEM kit for both rears.

Removed both rear knuckles, brought to Pep Boys, paid mechanic $80 under the table to do both, re-installed.

Make sure you mark the position of the eccentric washers on each knuckle.

Make sure you preload the suspension using a jack before torqueing the suspension bolts to spec.

I went ahead and bought a Harbor Freight press on sale to do mine, pretty easy. And also good to have around, as the fronts soon went, then the rears got noisy again 10k miles later (NAPA bearings, under warranty, 50k on the replacements, YMMV).

The ABS sensors are very sensitive to their position when it comes to popping codes. Push them in until the pickup sits against the wheel, then back off ever so slightly (I forget the spec off the top of my head, but its something tiny like 3mm).

For the front wheel bearings, how do I know if I have the 75 mm or 82 mm ones? I see both parts as "OEM".... THANKS IN ADVANCE!

1.8t pre facelift? are the smaller ones, I'm not 100% sure but I think facelift 1.8t have the bigger ones. AFAIK all the 2.8 are the bigger size.

all 2.8 and and i believe all front wheel drive 1.8t's have 75mm front wheel bearings. 2001 1.8t's have 82mm bearings. 97-00 quattro 1.8t's have 75mm bearings in front

Are the rears a different size? I have a 99.5 Audi A4 and would like to know what is on all 4 corners so I can get this done. Thanks

Thanks! My 2001 A4 1.8TQ ended up having 82mm bearings... $35 at Napa Auto Parts!

Do you need a bearing press to change the front bearings? i.e. - how easy is the front to do vs. the rear?

Both need to be pressed in and out. If you're having trouble figuring out what size you need shoot me a PM with your VIN and I'll see that you get the right one.
