unwanted variable camber

[nesralyrrej]

hey all, having an issue i cant seem to find anyone else having had.

my truck, A 90 d35 ranger seems to adjust its camber itsself.

when backing up it seems to lift the truck and therefore adjust the camber, its odd.

when going forward it will be in negative camber slightly, when backing up it has a little positive camber.

this has been an ongoing issue since i paid for an alignment for the first time, since my buddy sold his shop and i cant do them myself anymore lol.

this weekend i did a complete front end refresh (ball joints, double adjustable camber bushings, wheel bearings, tie rods, everything except the axle pivot bushings since theyre only 2 years old with poly bushings.)

my front end is definitely a little heavier than stock, since i have a custom front bumper with a winch, and a supercharger.

i did replace the coils with a slightly higher spring rate than stock for the ranger, i believe they were off an explorer or something, but i cant entirely recall..

lifting while changing direction to backing makes me think the alignment is off and the bushings are worn as the wheels would be changing direction slightly and dragging.

normally backing would drop the front end, if it did anything, since the torque movement is opposite of going forward, which lifts the front end

My ranger does this too (2wd) Never really looked into it as everything seems "tight" and it drives good.

But i have always been curious why.

It's because it's a twin beam suspension, the toe is a touch too far in, it's normal but you could toe it out a touch and it will stop or at least lessen... I always leave them at a touch of toe in

yeah scott that's defiantly fair, getting new tires and taking it to a "quality" alignment shop thsi week, so that could definitely make sense.

we shall get it swapped over and see what it does!

Too much toe in or toe out will definitely do that. Check alignment and make sure all steering components and suspension bushings are in good condition.

In almost 25 years I've yet to take a TTB or TIB rig to an alignment shop (I've read enough horror stories, and I like knowing how to do things myself) and mine drive fine with good tire wear... If you have already gotten an alignment that means the camber and caster are pretty good, grab yourself a tape measure and go under the radius arms at the wheel rim where it meets the tire, measure that, you want that to be about 1/8" bigger than the same height at the front of the wheel rim... that's literally all I've done and it works good, if it still squats when backing up toe it out a bit more but leave it a little toed in. After you make a change it is good practice to back it up 8' or so then go back forward to reduce the binding of the suspension.

Or even drive it around the block. Then re-check.

Adjust both tie rod ends evenly. Otherwise, your steering wheel will get off crnter.

set the alignment myself, suddenly it works drives great and had no crazy camber lol! thanks guys
