anyone know whats causing it?

 

its when the car squats as you boot it the tyres run on the inside edge....

 

or you need to sort out your camber

 

The only real way to sort it out is put a 6 degree rear beam on the back, it keeps the wheels in the upright position so it keeps the full contact patch of the tyre on the road.

The standard rear beam on squat gains camber and toe in, on droop it looses the negative and gains positive camber and toe out!

Poor design by ford!

 

Could it be weak springs ive fitted new orignal back shocks should i replace the
coil springs aswell

 

Barry, no matter what you do, if it squats at the back it will always wear the inside edges, the harder the spring you run and the higher the ride height then the better it will be, but its always going to do the same unfortunately!

 

anyone ever tryed shims mine sqauts quite a bit.

 

I'm in the middle of converting my Mk4 Escort to rwd and have been looking at the rear camber thing a lot, I'm having to raise the diff hanger so as to keep the rear wheels more square to the road, By raising the diff 40mm it makes a huge difference to the camber angles, and thats on a standard diff mount, if you could make a new diff hanger to raise the diff by about 20mm would it not have the same effect on a Saff????

Oh and it gives better driveshaft angles if the cars been lowered!!!!


IMO of course, so please tell me if i'm wrong

 

The angle of the rear wheels is affected by the positioning of the trailing arms relative to the body rather than the position of the diff. Moving the diff up or down would affect the angle of the driveshafts but not the wheels.

what about the rose jointed trailing arms? that would soon sort you out!

 

I ran shims on my 4x4 and they sorted it right out tbh, not that scientific but it worked

 

where is a good place to get them.thanks cossie.087.

 

I have shims on mine, my tyres wear pretty even tbh, got them from Gaybird at R&B motorsport.

hi steve do you now what mil they were.thanks cossie.087.

 

how do the hubs bolt on square with shims in there and do you have to mode the hub carrier so that the bolt head clamps down correctly and not just on the edge of its head as the hub carrier is at an angle?
