That is a grand offer for anyone stuck with burnt bearings and having discovered some bonehead has omitted (possibly even yourself) to re-install the spacer. My very first attempt at 'backyard' front bearing replacement wore out at much the same pace as was described earlier. The spacer was still there but must have spun, and wore a tiny bit, along with the inner races which resulted in some play when the again-new bearings went in. But this time I had the local garage press them in place rather than doing the tap-tap routine and preying the tightening of the axle would seat everything.

Another way is to take the front wheel off a junk yard car and use it to replace the assembly you have. Rebuild the junk yard wheel with new bearings and seals, of course.Original owner of silver grey carburetted 1989 Festiva. 105k km as of June 2006. 140k km as of June 2021.

I will try to throw in a few pics to illustrate how this works. In the rest of the

using inch lbs of torque or the metric equivalent. Here is a pic of all things
back together but the big nut not torqued.
Here is a closer pic of a torque wrench . Both standard and metric are on
the dial.
The next step is to rotate the assembly , read the torque it takes to keep the
assembly turning. Move the dial until zero matches this torque, check it again
to be sure the reading is zero while turning the assembly as shown below.
Now torque the axle nut to specifications or however you do it..
Put the wrench back on and measure the rotating torque. The new reading
will be how many inch pounds of torque your bearing is preloaded. Hear we
have a reading shown below.
A word of caution, it is important to subtract the static torque or obviously
the reading will not b correct. It is also important to NOT use break-away torque to start the assembly rotating. This break-away torque will always
be significantly higher than the rotating torque. Break-away torque shown
below.

and two: the spacer is matched to the KNUCKLE, not the hub. the hub has no machining spec other than the OD that should be a ~.003" interferance fit to the bearing ID.Last edited by nitrofarm; 05-13-2012, 03:08 PM.Some people like to read fiction,I prefer to read repair manuals. Weird I know-

Nitro, I have never heard of those specifications or that tool ! I am always interested
in learning new stuff...?!
I will post a pic of this out of my manual, but note that what I do bypasses all the
steps but takes an accurate reading of just the inch pounds of rotating torque..increase
no other parts are included in that reading. I do it this way when I am confident
the shim is correct and will be left there.
It can also be used to accurately check specs with out disassembly.
anyhow the pics of my tool in use are above, here is a pic of the specs

If everything is new, like after a wreck I try to hit the 12 inch pounds. The more used
parts present the more I head to the middle range. If just checking a used assembly I like to see something above the lowest...Like after a wreck and the insurance specs out

Movin: I wonder about that technique because when I replaced my bearings and torqued the axle nut the wheel was really stiff until I put the tire back on a drove up and down the driveway. Seems the weight of the car seats the bearings? How would I compensate for that in the test?Last edited by WmWatt; 05-14-2012, 11:55 AM.Original owner of silver grey carburetted 1989 Festiva. 105k km as of June 2006. 140k km as of June 2021.

drive it to seat the bearings, then loosen the big nut and get your static
drag reading , tighten the nut again and measure your total. Subtract
the static to read your actual preload.
The tools are supposed to get things seated but sometimes a little
massaging with an air hammer or big dead blow on the knuckle and shaft end can seat them too. If there is any doubt a test drive would be best.
Again, this is a quickie for when you are confident the spacer is correct,
you want to check a used assembly, You just replaced bearings and are
reusing the spacer, that kind of thing. To guess at new shims and use
this to check specs would be no quickie!!
Thanks for bringing up stubborn bearing seating!Reflex paint by Langeman...Lifted...Tow Rig

Make sure as you are torquing the nut. You are spinning the wheel/hub. It will help.
PS dont forget about seal friction/drag.Last edited by nitrofarm; 05-14-2012, 12:32 PM.Some people like to read fiction,I prefer to read repair manuals. Weird I know-

Dude, you got some awesome tools!!! We should do an album of cool
tools!!
Q= How far are you seating your seals on the inner/outer? I'm really staring to second guess my thought process on these.droolSome people like to read fiction,I prefer to read repair manuals. Weird I know-
