Front Bearing Replacement

[AimCOtaco]

yep, same grease should work.

My fronts came apart by finger as well just a couple thousand miles after a "qualified mechanic" put on rotors. Thats why I think the 35lbs is the way to go.

Thanks!

Ordering some parts to do wheel bearings. Should I replace the lock nuts or reuse them?

If they're not torn up by a previous "ham-fisted" mechanic, I usually take them off, hammer them flat again and reuse. Others replace them every time. Your choice. They are cheap compared to bearings.

As super said, but make sure to change the inner hub seal !!! And check spindle bearing.

Thank you. Is the spindle bearing easy to access? What should I be looking for visually to see if it's in good condition?

Push the axle shaft in so that you can see it behind the hub (the CVs will give a bit so that you can see about an inch of the shaft on the inside). All you need to do to push the shaft in a bit is to take off the c-clip outside the hub.

It's good if you see fresh grease with a pattern created by the bearing rollers. If you don't, then take off top or bottom ball and swing the hub off the shaft to investigate further.

This is what a good one looks like:

Then add a bit of grease before pushing it back.

uHu - is there a way to check to see if the bronze spindle bushing needs replacement? Any symptoms to look for? I'm thinking excessive clearance behind the C-clip could be one of the signs of a worn bushing?

Wow, thanks for the detailed and helpful information guys. REALLY appreciate it. Also, is there any chance that the play I get in the wheels and the audible noise I hear is from the spindle bearing and not the wheel bearings?

RTH - In my 03, FSM, it states to torque the adjusting nut to 43 ft/lb. Now when i do that, my hub spins as freely at 43ft/lb as it does when the adjusting nut is loose. Am i doing something wrong?

This is a highly debated issue, on the 80-series board, as I remember.

It has always been my experience that if I torque the adjusting nut to spec and then test with the fish scale, I am far below the force required to turn the hub relative to what the FSM says it should take (12 ft-lbs is the middle of the spec range and I'd be at 3-4 maybe). The two specs seem at odds (thus the debate in term of how to reconcile). Last time I did it, I torqued to get about 6 or 8 ft-lbs on the scale, which put my torque on the adjusting nut significantly greater than the spec required. To get to the 12 ft-lbs takes a LOT of torque on the adjusting nut. More than I am comfortable with. I find a balance between the two: the hub is solidly on there and there seems to be a reasonable amount of preload (resistance).

Others will chime in, but that's the way I do it. YMMV

Bearing repack or replacement


12. Retighten the nut to 38-57 in-lbs (4-6 ft lbs). I did this by attaching the spring gauge 10 inches from the center of the nut and tightening to 6 lbs.
13. Check that there is no looseness on the bearing.
14. Using the spring gauge (fish scale), measure the preload of one of the wheel lugs in the 12 o’clock position. The preload should be between 9.5-15.0 lbs.

I believe my '99 FSM states 43 ft lbs for step 12. and 27 lbs for the spring gauge in your step 14.

What's the best way to tell if your wheel bearings front and rear are gone without jacking up the car or removing wheel.Thanks.

It's going to be difficult, because if you think you feel a little bit of play at 3 and 9, that could be something within the steering components. You need to get the front wheel off the ground to check for the slight movement at 12 and 6.

Guys just a question took of my wheels to look at.my bearings and both the cover caps on each side that come off with a screwdriver etc have been mig welded around the cap ????.Never seen this before cannot get cap off.

 

[uHu]

Wtf. Pics?
Time to get new caps, and then a grinder.

 

[Greenbean]

Wow man,
I surely hope that's not true.

Pics please, sorry for ya man but it's fixable.
