I helped rebuild the front end on my Swinger with all new (PSG)components long ago w/o the motor (340) in it. Yesterday, when I lowered it off the jack stands the front end sits VERY low. It's obviously way out of adjustment.
I need some knowledge on torsion bar suspension and how they work.
thanks
Mike

Tighten the bolts the car goes up. Loosen them and it comes down. I prefer to do it on an alignment rack with the pins pulled in the turn plates. NIce and level, no need to roll the car to settle the suspension and plenty of room to work.

crank up the tbar bolts to get the ride height to where the height & rake of the car looks right for where you want it & do this with you in the drivers seat & fairly level from side to side. The alignment shop may not even have a spec for our stuff & even if they do you can(& should) set it ahead of time to where YOU want it. I would also loosen the UCA & LCA bolts right now as if they are tight & you added the eng the change can twist them too far out of their normal range of travel. At the alignment shop set barbells in the drivers seat to match your weight(& a half tank of gas),have the alignment guy tighten the UCA cam bolts TIGHT when he's done & give him some green to take his time & get it right. I got mine right & it just floats down the road.

thats alot of bar bells...lol...

the torsion bars aren't budging with 15/16 socket and the 1/2" ratchet and old guy arm power.

My compressor blew up so that's out.

Never a good idea to use a hammer, but would I hurt it if I whacked on the rachet to get them to move?

it's on the ground, which, according to the FSM is where it's supposed to be sitting to adjust height so i'm assuming this is correct.

thanks

Mike

Dont I know it. I think it's that McDonalds that opened across the street EDIT yes on the ground with you in it & I'd spray the adj bolts with your favorite brand of penetrating oil & let sit for several days if necc with repeated sprays & use a piece of pipe on your breaker bar. No hammer.

Jack the car up then adjust the bars. Then set it back down and bounce the front end. It isn't necessary to have it on the ground to adjust. I've done a a lot of Mopars that way. The weight of the car makes it very hard to adjust. Are you sure about the bolt head size?

yeah- 15/16" is way to big for torsion bars-
3/4 as I remember. 15/16 is for front of strut
rods I think

I walked away from the torsion bar question until I heard from you guys. I jacked it up and tried to turn the drivers side with the car off the ground...doesn't budge. I moved onto trying to figure out why the heater blower doesn't work. Water up leaks too.
I will check that socket size.
more to come
thanks
Mike
