rear end squat

[roy67ss]

OK, I've been reading most of the posts on this subject, there is lots of them!, it seems that most agree that it is in all likelyhood the yokes, if the rods aren't bent and the spindle bearings are good. Those parts are OK on my car and I have the cam cranked to the max on the rods. Still about 1/4" difference top to bottom of the wheel.
Is it also possible that a worn out leaf spring could result in the same appearance ?
My tires don't appear to be wearing on the inside yet!!

I can tell you that my rear leaf was "worn out / weak". I replaced it with a VetteBrakes mono-leaf. The car sit's pretty.

Squat are you talking about?



Do you mean "The Squat" when you put your vette into gear, or do you mean it squats when parked and sitting still?

By squat I am referring to the rear tires appearing to be much further out at the bottom than the top or leaning inwards when viewed from the rear.
Various posts have referred to the yoke. Are they referring to the spindle support in the figure attached below?

I don't think so...

That pic is of the trailing arm assembly as it connects to the wheel.

The yoke is actually on the rear end. Side yokes come from the rear end pumpkin and guide power to the half shafts to turn the wheels.

My yokes were bad and we had the whole rear end replaced about 9 years ago. My tires were slanted out at the bottom and the insides of the tires were chewed away! I also had a moaning, groaning noise starting from a stop and going around slow corners.

You may wish to search C-clip or ask 69MyWay about the C-clip because I recall him talking about it, but I can't remember in what application he meant. I think it holds the yoke and spindle assembly together, but don't take that for the truth! I am only vaguely remembering the conversation.

a few minutes later:
I checked my Hayne's and in the driveline chapter I found a drawing of the side yokes. When looking at just the rear differential, the yokes appear on the side of the diff housing, where the u-joints connect the half shaft to the differential.
Hope this helps.

Squat

Many factors apply here, Springs can cause it to sit LOW but the squat can be fixed IF you have good bushings in the link arms.

If a bearing is out ( or you think it is ) you have to jack the car UP and check for bearing play FIRST.

So... on my 73.. I got new bushings for the link arms.. and had the springs replaced.. and an alignment and BINGO no more squat!

If the link arms were hammered on for alignment... replace em or get the aftermarket adjustible type.

From what you described it sounds to me like the word squat should be changed to camber(top of wheel leaning in). smart struts from vette brakes. MERRY CHRISTMAS
