Rear Camber

Does anyone know how to camber the rear besides a IRS?
It for a 94 toyota pickup

 

reverse into a couple curbs at 50+ mph until desired camber is achieved?

 

lol no.. I swear someone posted about it on here

 

anyone

 

on a solid axle?


like, for real?

 

Can be done to steel housings with cold bending. Or you could buy a housing.

it for a 94 toyota pickup single cab. So which one suggest and there no prices

 

im confused how that is even possible, you would be trying to bend the axle shaft then as well...

 

idk heard you can different stories on here one was shims and something else wiith the wheel bearing

 

I'd put a couple washers on 3 of my lug nuts on each wheel and park strategically.

 

It's pretty popular with circle track guys and dirt oval racers. Housings can be bent to around 2 degrees and still have a decent lifespan. Yes, you are bending the shaft as well but shafts are flexible. It's pure hell on just about every component but it works.

 

Haha that pure hell is what I figured. I can't imagine the bearings last long at all!!!

 

Bending the axle housing does NOT bend the axle. If you look the axle is supported on the outside (tire end) by the wheel bearing. It's next point of contact is where it contacts the differential slipping into the spider gear. If you bend the axle housing, you just cause the wheel bearing to move upward as you bend the housing, which slightly tips the entire axle shaft higher. Only drawback to this is that now the axle shaft is no longer going into the differential at a perfect 90 degree angle, it is tilted upward however far you bent the housing. There is a tiny bit of room for play, but going above that and the axle splines are going to wallow out the female splines in the spider gear and the whole thing is going to fail.

If you bent the axle, first result would be MAJOR vibration, second would be wheel bearing and spider gear failure with the axle shaft running in a wobbling path.

 

So you are saying that there is ZERO deflection in the shaft when the housing is bent?

 

Didn't say that at all. The axle is held by a bearing on either end. If you bend the housing upward, then that end of the axle is now deflected upward, but the axle itself remains perfectly straight. Now the other end of the axle is entering its support bearing at an angle (not good for bearing life) and the splines are entering the spider gear at an angle (also not good for spline longevity.

If you bent the axle, it would be undrivable. Here is a simple test. Take a 3' piece of wire and support it on both ends by a piece of cardboard with a hole that fits closely. Now bend that in the center by a small amount. Put it back in the holes and grab one end and spin it.

1. Look at the other end. Notice that it is wobbling? That is connected to your wheel hub. Doesn't take much wheel wobble to shake your teeth out.

2. Look at the opposite end, this is the end going into the differential. Notice that end is wobbling. Imagine what that is going to do to the splines over time. One day you get on it and nothing but a grinding noise as the splines are gone and the spider can't transfer power to the axle.

Bending the axle housing sounds like an incredibly bad idea to me. Bending the axle sounds like an impossible idea. You really do want things to enter a bearing at a 90 degree angle. Not 89 or 91. That puts a stress on the bearing it was never designed to handle.

That's why everyone that goes to a lift kid immediately encounters driveline vibration. A u-joint works best at a zero angle. That's why front-wheel drive vehicles use a CV-joint, this works well over a wider angle (and which is also more expensive and heavier). In a traditional U joint, if the angle of the input shaft and output shaft is not 0.0 degrees, when you spin one shaft at a constant RPM, the other shaft has a speed variance that is proportional to the departure from the zero angle. So drive the front of the shaft at a constant engine rpm, and the wheels try to change their speed as that U-joint wobbles around, and you get shudder. It is MUCH worse when you don't have a u-joint, as in the rear axles.

Hope that helps...

 

yeahh youuu

 

Yes, you did.
Uhhh yeah. OK.
I installed a lift "kid" on my '12 and immediately encountered no vibrations.
True.
Partly true, axle shafts are not torsionally rigid. If they were, my welded D70HD would have exploded long ago running Michelin 395/85/R20's as a DD.
Hope this helps

 

I've been following NASCAR for years, and although I can't say for sure that they do this now, at one time they ran rear castor by using specially made rear end housings, and then the rear hub floated on the end of the axle. Probably not correct terminology, but that's what I remember.

 

Robert - excellent description!
