Why? Drivers side higher than Pass side

Postby mojogoat » Tue Jan 29, 2019 7:01 pm

I measured both front and back and the driver's side is 1" higher than the passenger side. Don't under stand why unless something heavy was carried on the passenger side. The Leaf springs have what appears to been wooden wedges installed?

I wasn't going to respond to this, but alas: I think we all agree that it didn't leave the factory that way(!!), so from what I've seen for possible causes: A previous owner was out 'stumping' with it. It might have been rolled, and the top of the cab would show that evidence. Or it's been "airborn" and came down hard, but unlike the General Lee and Daisy Dukes, your underpinnings got bent. I'd look at your shock towers and leaf spring shackle attachments for cracks/disfiguring, and other signs of bottoming out. The wooden wedges are a novel idea, I'll have to remember that one. If the truck still steers straight, is otherwise driveable, and tire wear isn't out of the ordinary, I'd just keep on truckin'. Does your WA State title say "salvage" across it? (all my vehicles do). That might explain a lot. Don't know which county you're in, but most do not have vehicle inspections. Outside of a wreck, I suppose plain, old, spring fatigue can be blamed, but then every vehicle out there older than 1982 would need new springs. Regardless, it sounds like your rig has a colorful history!!

One front torsion bar out of adjustment mihjt could cause some of the leaning.

Spent allot of time cleaning the undercarriage ,didn't see any cracks or evidence of major damage, gaps normal, bed alignment/gap normal,. surprisingly the undercarriage doesn't show as much wear and tear, or rust for a vehicle of this vintage coming from Oregon. It steers straight and it seems most of the front end parts have been replaced recently. Checked the gaps when I sat in the drivers seat; it lessoned to 1/2" difference total. Maybe one of the previous owners weighed more than my 225lbs and sat in it while being aligned.

Id take it to a line up shop and have them adjust the torsion bar tension on eaxh side so they match. The rear may fix itself, or they may find a missing shackle bushing.

I like Puttputtinpup's last answer. There is a procedure for ride-height adjustment on torsion bar suspensions, if you're curious about the procedure. There's a u-tube video titled 're-indexing torsion bars an Mazda B2200 and other pickups' and it looks pretty scary to me. One snapped or stripped rusty bolt and you've got a 3000 pound boat anchor! Another cause could be somebody overloaded the truck, repeatedly, like hauling firewood or a home-built camper.

Just sprayed the adjusters with penetrating oil, noticed one side adjusted more than the other. I'll mess with them a bit before I get it aligned.

If the leaf springs are already sagging, matching the torsion bars will help, but the rear is always going to be a little lower, I would remove both leaf packs and checking them out of the truck, a cheap quick fix is replacing the 2nd leaf spring.

I removed the thick lower leaf and installed an overload leaf on both sides.
Installed air shocks, 30psi
Adjusted torsion bars.
7" clearance on rear
5" on front.

I installed a plugin behind the license plate for the block heater, battery minder, and fuel filter heater.
