reset torttion bar

[Chris S]

 :help:I m wondering how to reset tortion bar Iv got a 90 Toyota pick up. I bought from a buddy the guy he bought it from cranked up the tortion bar

uncrank them... at the end of the torsion bar around the middle of the truck, there are some big bolt heads that stick down..... you put a wrench on them and turn it until you are satisfied with the way it sits... then go get an alignment

WARNING!!!

I recently started to re-adjust (uncrank) the torsion bars on my truck (late, Sunday night - quick adjustment... ). To make a long story short, because of rust buildup, BOTH of the adjuster bolts broke. I had a spare set on hand already, so, I was not cursing and throwing tools. They are easy to replace (once they're broken).

Word of advice: use a small amount of grease between the bolt head and the lower pivot bushing, to prevent rust from seizing the bolt to the pivot bushing (moisture can collect in between), and use anti-seize on the threads.

another tip is to have the front wheels off the ground hanging... it will put less stress on the truck.... have it supported by the frame....

good point tonka....I always make sure I have an extra NEW set of bolts laying around before I touch em

Ok on those bolts there should be 2 nuts undo the small nut from the long nut before trying to back the torsion bars off if you don't you'll be wasting a lot of energy and wondering why it isn't working. Only take out a few rounds per side and then check your height, then repeat until the desired height is reached. Then tighten the small nut against the long nut until they are tight against each other.

I have a 2wd that the adjusting bolts have the 2 nuts, but MY 4wd only has a single nut (same with the replacements). I don't know if or how often they were interchanged, so don't be surprised if you have only the single nut.

edit: Not doubting, just my observation. I agree that the 2 nuts would be more secure.

And yes, lift the front end. You will REALLY be putting too much effort into it if you don't.

Never come across a single nut, the reason for 2 is to keep it from backing out.

This is the style of nut/bolt that is used on my '90 and '91 4x4's.  There wasn't a second nut on either.

Those are the same ones I used.

UPDATE:

I just finished working on my truck this weekend, and looking back over the truck (been a while since I've checked everything), I checked the t-bar adjusters. I grabbed a socket and gave each one a 1/4 turn without jacking the truck up. It took relatively little effort, but the nuts and bolts were still in the same position as when I installed them back in August (I marked them back then to be able to see if they moved). I have made a few muddy runs since then, and almost everything under the truck had dried mud on it, but the threads on the bolts were pretty clean. I would HIGHLY recommend that you grease thehead of the bolt, and anti-seize the threads!!
