Re: Minimum Lift Question
It depends on the bearings I believe.
Something like a CJ has cone bearings and adding a spacer stresses the
crap out of them.
I have read that the sealed hub unit used on the Cherokee, YJ and TJ
uses flat bearings so the spacer has way less 'bad' effect.
The cone acts like a lever for stress.
I could be off base here but don't think so.

Re: Minimum Lift Question
I can understand how decreasing the backspacing would put additional stress on
the bearings. Where I am confused is how does the bearing "know" that the
additional stress is coming from a spacer vs. a wheel with less backspacing?
Everybody says spacers are bad, OK, but why? Assuming we ignore any increased
bearing load what makes spacers evil. I know my state doesn't accept them
either. But, they didn't blink an eye at my truck, and like I said before it
came from the factory with big spacers.

Re: Minimum Lift Question
The difference in strength between the spacer on a one ton truck,
is the lug bolts go though the space:
http://www.hotrodders.com/attachment...&postid=379783
Where the spacer you're using on your Jeep uses another set of bolts in
that adapter plate to attach it to the rim.

Re: Minimum Lift Question
The attachment point is farther away from the center of the bearing
set. This puts the stress directly on the outer bearing. With a normal
attachment point, the tire is gradually moved out farther by the rim
shape.
The end is the same so yes having a modified backspace will cause faster
wear on the bearing no matter what, it is just less of a load than the
spacer gives.
Think about a teeter totter. You can put a smaller load on the end to
over balance it or a much larger load up close to the pivot point to
balance it the same or a massive load right on top of the pivot.
Once you get out past the center balance or pivot point for the bearing
set, the down angle radically increases stress. When the direct hit is
straight down on the bearing, it should last longer.
I think that makes sense.....
