Title: Is it possible to repair damaged front knuckles for new bearings?
Post by: DavCorn on May 12, 2016, 01:25:29 PM

Hello,

Russ at RooSports suggested I contact the forum.

I believe through some poorly done front bearing jobs (multiple on both sides) my knuckles/hubs are damaged and not accepting new races and bearings.  New bearings are going bad within months.  I am hoping it is the mechanic and the jobs were just done poorly and there is no actual damage, but we can only tell that when the current bearings are removed.  I'm having a new mechanic do the next install.

If there is damage, has anyone here on the forum dealt with this problem.  Replacement knuckles for the XR2 are not available. I have ordered new hubs and will install them as needed.

Can the knuckles be machined/cleaned up, so as to accept new races/bearings/and spacers?
Any other ideas?  I would rather not downgrade to the non-turbo knuckles and rotors that Russ has available.

I really want this to be the last time I need do bearings.

I had ordered the new knuckles from Russ, but canceled the order when he let me know it would require replacing the brake rotors with the smaller size.  I didn't want to go there.

Sad that I missed those. Anyone else have a set in good condition?  Not sure if I need them yet.  Anyone have any experience cleaning/fixing them if damaged from bad bearing job(s)?

What kind of damage has been done to the knuckle?

Have the new mechanic follow the FSM procedures for checking preload and selecting the proper preload spacer if you have them done.

I highly doubt your knuckles are bad. As long as you can still fully seat the bearings, they should be ok.

I’d guess the bearing failures are from improper installation from things like mixing up the preload spacers, dead heading a press when reassembling, or improperly torqued axle nuts.
