Front wheel bearings replacement help

[hemmah]

Forum,

I need my front wheel bearings replaced. I see inside and outside bearings in the new part selection. I also see one seal in the new part selection not two seals.

• Don't I need to seals - inside and outside seals?
• I would like to read the technical article on replacing wheel bearings. Did not see this in the Tech Info Center. Please help with instructions or a Web site to instructions.

Thanks
Steve

Well - I just did mine about 3 months ago. My inside and outside seals looked like new - however all of the work to get it apart, cleaned, etc., I still replaced them. They are not that expensive.

Look at it this way. You get everything back together and in 6 months - an inside seal leaks. Okay - tear it down again.

They are relatively cheap - replace them

Only one (inner) seal required per wheel.

Here is a good video link to you tube. It should help you do everything you need.

Oh, only one seal needed. Ok I can buy now.

I read a few Threads on Front Wheel Bearing replacement. Replacement is more difficult than US cars with heating and cooling needed to replace a 911 bearings. Do I really need to heat the hubs and cool the races?


Thanks

I did mine this summer... put the hub on the grill and the race in the freezer. It did make it pretty easy to knock out the old one and put in the new one.

I have not done this yet, but I saved this link for reference:

Paul’s Garage Blog » How to replace the front brakes and wheel bearings on a Porsche 911SC

Hope it helps.

Just like chrisbruck said...personally I like my hubs medium well...and I cooked a couple of steaks on the same grille later that evening as a reward for my hard work The light aroma of bearing grease complimented the cheap wine to perfection.

Get a good thick pair of real leather gloves. The hubs will be hot and those fake leather mechanics gloves will melt!

I did the same as AJ and Chris. Went to my auto supply house, asked for P car front bearings/race. Crossed over to Chevy bearings/race! Installed them 4 years ago, no problem. Cheap too, around $30.00 for both fronts. If you need P/N, let me know. They were FAG bearings too, not junk.

I used the oven. If you clean them perfectly it will not stink. You do not want to overheat the aluminum as it may fatigue the metal

I use the grill too for these types of things. Best to use some welding gloves to pick them up.

Was about to heat my front hubs in order to remove the bearings and thought twice. First, having read this post, I think I will use the outside grill rather than the wife's range...
But do I need to clean them thoroughly first? I am thinking of heating a (not very) volatile but still a petroleum product over a flame...
Any thoughts?

Sidenote: what type of blasting would you use on hubs to get them like this?

Plastic media works great:

Just bought a Harbor Freight blast cabinet. Haven't even set it up yet, but can't wait. What is plastic media? Haven't really looked around yet so excuse my ignorance.

Also, didn't mean to hijack the post but can I heat my hubs on the grill without having cleaned them thoroughly? A bit of grease still on them... Planning on using the outdoor grill...
