View Full Version : A few wheel bearing questions

My front driver's side wheel bearing is on its way out. Looks like a pretty easy DIY job other than the whole "needing a press" bit. I have a couple questions.

1) Do you need an alignment afterwards? I've seen this question asked on half a dozen threads on various Audi forums.... all of them dissolved into an argument. Anyone here NOT had an alignment after and seen uneven tire wear?

2) In a similar vein... should I just replace the front passenger's as well?

3) ECS carries the OEM, Rein, Vaico, and Ruville brands. Is there a brand to avoid or can I just go with the cheapest, in this case Vaico.

I done a few front bearings without having an alignment. Never had odd wear from it

I do one at a time. When it goes, it goes. Might as well get as much use out of it

Just get a F A G from Rock Auto. Usually around $40

Pick one up at FCP, can't beat a lifetime warranty

This. FCP sells good stuff. Warranty helps

F A G and SKF are good brands. Beck/Arnley is not a manufacturer. They relabel most of their stuff. Usually good quality. You should replace the axle bolt. In general you do not need an alignment. However if you have never had an alignment done where they adjusted front camber with a subframe shift, you probably need one.

If you want a locally available (but very expensive) lifetime warranty bearing, you should be able to find a Moog bearing somewhere, which is just a National bearing. Wont be cheap though

Had my rear bearing done twice both times without an alignment. Never heard of needing an alignment. Go with a F.A.G. bearing. Idk what mine are.

Alright thanks guys I'm gonna go with a F A G one.

I asked about the ECS brands because I currently have a gift card. I'll just use the card for something else though. I've got a coolant leak (I suspect the flange[>_>] ) so I'll pick one of them up too.

I have never used a press but I also live in an area where rust is not an issue as you can see the below the dirt just washes off and there are painted surfaces under there. I have heard some people have to work a press hard to get theirs out so take it as a warning that some do and some don't. If you use a hub shark like in the pics below you don't need an alignment but if you are pulling the knuckle you should, front not as much so but rears for sure. You also have to replace the hex bolt that holds the hub to the outer cv because it is a stretch bolt. For the fronts I just broke the stretch bolt with most of the weight on the tire and then put the car on jack stands. I don't live in the rust belt so I pull the pinch bolt so I can pull the knuckle out to get the cv out of the way and then use a hub shark and some home made crap to pull it apart. You need a tool to pull the outer hub, one to pull the bearing, and a bearing splitter to pull the inner race off of the hub. This is for the rears but the concept is the same..

Thanks.

I read about needing a press. My friend works in a shop that's like 3 mins from my house so I'm not concerned about that.

Here's hoping the rust didn't too bad. I almost gave up doing my upper control arms last fall because of the fucking pinch bolt. FUCK that bolt.

Both mine slid out like butter. Well, after I got the BFH lol. Took only 2 mins of hammering and it was free. I too live in the belt of rust

ECS sells F A G bearings so you can use the gift card.

If you rent a bearing puller like Corrado_Guy has there is no need for an alignment and you don't need a press. I just did my 97a4 rear bearing the other day and it was original with 265k kms on it and I live in the rust bet and it was in there GOOD, once it popped it slid out like nothing. You have to heat the knuckle opposite the abs sensor and it makes it come out a lot easier.

Just did my rear passenger side. Used a F A G from FCP.

I pulled the whole assembly out and had it pressed in/out at work. I did not get an alignment.

However I did mark my alignment eccentric bolts in relation to the parts they were on--and put them back to the same orientation when I assembled.

Alright thanks guys I'm gonna go with a F A G one.
.

If you can find SKF brand bearing, then go for it. Else get F.A.G one..
