Front wheel bearing spacers

[denguy]

How can you tell for sure if you have the correct spacers in your knuckles?

[FestYboy]

aside from the spacer selection tool set, proper use of a micrometer to measure the machined gap between the race seats +.001-.0015" and double check the turning torque.

remember, each knuckle is unique within a specification window. and the spacer that came with the knuckle is a non-wearable piece and never needs to be replaced with another unit.

What he said. When you pull the old bearings out, keep track of the spacer and make sure you put same one back in.

Front wheel bearing spacers

As long as the bearings are machined exactly the same with no imperfections that would work. I reused the spacers on my aspire with timken components and the right side was way too loose ( spacer too thick) drove it for 5 years like that then ended up finding the spacer selection tool at work and bought all the spacers. It had a 13 in it I believe it ended up using a 10 or 11 to get the proper rotating torque

AspireSVT.........what is the difference in thickness between a 13 and a 10 spacer? Also what was happening to the loose right side wheel you wrote about? I have a shake in my front end that I can't find the cause of. Thanks

I've been noticing the exact same thing when doing my pre load set ups. I've been having to go 2-3 sizes smaller.So that tells me there has been a change in bearing manufacturing.

They are sized in MM thickness but to give you an idea the difference between a 10 & 11. The 11 would be 1.6 thousands "Thicker",giving you less "Pre load". If yours is loose denguy,you might be getting the shake from the rotor not running true. I experienced the same thing with a loose bearing setup. If you put the same spacer back in you are just hoping its good.I know thats what a lot of folks do and it'll be ok. But if you want it right,you have to check it right.

What is the torque mentioned above? Wheel rotation?

[WmWatt]

Do a search. People have posted the spacer chart in this forum, also the procedure to select the proper one.
The old spacer should work with the new bearings because the bearings are all made to specifications. The spacer is not subject to wear as it is stationary between the bearing gages.
Often the wheel will be tight when the bearings are replaced until the weight of the car is on them for a few rotations which sets the bearings. If the bearings are loose try tightening the axle nut. It's hard to get it torqued to spec by hand without a handle extension and full body weight.

Kia still sells the spacers for the rio, same parts!

[denguy]

I was thinking there was a torque spec for how much it took to turn the knuckle after assembly showing the bearings were set right.

Click on "Check this out" (its a link) then just scroll down to the post number #24 like driverone stated.....When you get there the VERY LAST image is actually a video (poor quality i know) but it shows how quickly the pre-load process can actually be checked.Good luck,isnt there a member close by in FL that could help you?

In nitrofarm's post above, put your cursor on the words "CHECK THIS OUT" and click on them. That is a link to the post.
