aligning back axle

[kirk10]

after you have fitted a atlas back axle to a mk1 escort with 6 link bars

how do you make sure every thing is aligned properly

 

i could set the 4 link bar threads the same but what if the body boxes or a mm or 2 out

would scrub the tyres

 

just want to make sure every thing is proper the first time ?

can you not jack the back end up and, using bob weights from two points on the chassis, mark these points on the floor then do the same with the axle and measure betwwen the points both forward/backwards and diagonally

[Conor]

Measure the distance between the centres of the front and rear wheels on each side and then measure the diagonals which is a bit harder to do.

 

That should get you near enough to take it to a proper place to get sorted.

Gave this a lot of thought when I installed the 6 linked axel in my Tina

 

I understand the concept of measuring In diagonal but where do you take the measurement from

 

As with ford cars most of the time could be up to 1/2" out per side

 

Think it must right as she seams to launch well enough

 

Watching this thread with interest

you just gotta find a common feature thats on both sides of your car and measure diagonals across them to common points on your axle. itd be pretty hard to get it bang on the life some of the shells have had being thrown around bends all their life as long as the back end dont start steering for you when you drive it... although youl prob be doing that intentionally anyway with the tyres alight

i can borrow a 4 wheel lazer tracking system from the tyre centre i used to work at

 

but with them you set the fronts paralel with the back then your plus or minus tow in or tow out

 

so really need the back to be right first then use the tracking gages to line the front up

 

but saying that the lazer tracker might not work as ive altered the width on the rear axle from 48 inches to 52 inches
