DIY: Front wheel bearing's

Hey all, back from hiding yet again, I figured because I had to do this again due to a bad bearing (timken bearing too which surprised the hell out of me, 1st I've ever had be bad in the 13 years of being a mechanic from them) on my 2010 S2 sport, this is just a guide line and should only be taken as such.

So here we go....


This is basically what you should need, (minus a few things but will hit up on those as we go along) and be sure you are on a good flat surface due to some impending force that will be needed, take the wheel off and you will be here.



Now you take off your caliper and hang it out of the way as such (2 14mm bolts for the caliper and 2 17mm bolts for the caliper bracket) then take off the bracket.



This can be a pain but with an impact screw driver it makes life easier, if you don't have one just grab a screwdriver you don't care too much about and a hammer and carefully smack the back of the screwdriver (BE CAREFUL, you could easily make projectiles here with a cheap screwdriver) while turning to break the tension/rust, I have a breaker bar here just to hold everything in place while you do that.




This is the new timken hub that is NFG and new so it was easy to come out but know from here you are going to need some muscle, a slide hammer and PB blaster.




Be sure to remove this plug, you will need a small pick and pry down while pulling out.




Another shot of the back side and the 4 bolts you will need to take out.




You WILL need this (slide hammer kit) as well as a good sized hammer and take your strong pills (rarely they come out easy, most times it will be quite a bear to get out, the first was for me)




I have old lugs just for this but you can use the original ones, just know you can and probably will mess them up.




This is how it should look assembled, watch your hands and get ready to put some muscle in to it.




Its now out, note that the backing place is just riding on the back and will fall out.





This area though tight tolerance can and will build up surface rust (another reason why it can be a pain in the *** to come out) so be sure to take some sandpaper to the area and get all the rust off.


Now I am going to be waiting on the new one but installation is reverse of what you have seen but minus using hammer time, on putting the new hub in be sure to walk it in by going in a x pattern with the bolts and make sure it is flush with the surface before you put a torque on it. (Torque specs here: https://www.rx8club.com/series-i-tec...eel-hub-85147/)


Good luck and be sure to get an alignment after!!!!

mine wasn't nearly as difficult to get off... did both sides by hand without the kit, not sure why yours were so difficult? I did both left and right fronts by hand while at the track... not sure why yours were stuck though...

also - going with extended studs in the replacement?

Would want a better set of wheels before extended studs tbh, As to why it was difficult, it was my DD for about 1.5 years in Maryland and they love to put all sorts of salt down everywhere when there is even a slim chance of snow.
