Guys, I know this has probably been discussed many times already but the search function seems to be limited to posts within the past month or so since the website got the new format. That or I just can't figure out how to do a proper search now. Anyways I need to get my OEM torsion bars out from my 1973 Charger to swap in the new 1.06" FirmFeel units I have. I don't have the "correct" removal tool. I have done the vice grips and rag in the past which usually doesn't work all that well. Anybody here have any ideas on how I can clamp down on these good enough to knock em free? I have some 2x4 wood scraps and various bolts. I think I have seen where somebody used two pieces of wood and bolts to clamp down on them. Can anybody here clarify how that is made and how well it works? Any other ideas? I don't care if I scuff the paint on them as I don't plan to re-use them anytime soon but I would like to try an avoid destroying them if possible. Also is this the correct steps to take to do this? - jack front of car up off ground to unload suspension - take off control arm bumpers - back off adjusters all the way - remove clips from torsion bar mount - remove torsion bar Also, I know that there is a L/R torsion bar but is there a front/back end or does it matter? I seem to remember that it didn't but I thought I should go ahead and ask. Thanks!

no front/back ex some have an ID number/letter combo on one end & if so I put that end at the rear so I can visually ID it at a later date if need be (plus mike the dia). I would suggest not marring the old ones as things might change later & you might need or want to sell/trade them. have the tire/wheel off & jack up the LCA just the right amt all to get everything as light as possible and in a straight line as possible & on A bodies I tap the front LCA tapered stud rearward a bit to get the whole scheband moved rearward some then on the rear side of the Kmember tap the LCA forward to get it to come forward from the tbar hex then it is easier at that point to get the tbar able to be moved rearward/free to seperate it. grab a helper if you can.

The steps on your list look right. I usually spray some penetrating oil where the bar goes into the lower control arm and also pull back the boot at the rear of the bar and spray in that area too. I use a lead hammer to smack the sides of the bar where it attaches at both ends to help get it loose after you have unloaded it. If you plan to save the bar you will want to try not to nick the surface of it. The correct tool do make a big difference on stubborn bars. The good news is the car only has around 1000 miles on it with the current bars and I did the grease thing on both ends when I installed them. Hopefully they won't be too badly rusted. And no, I don't want to cut them in half in case I want to re-use them later.

You can just remove the large forward nut on the LCA pin and use a BFH to break it loose. So would i have to seperate the lower balljoint then to free the arm or not?

The idea is to pry the LCA towards the back of the car, thereby pushing the t bar out of its socket on the trans X member. So long as the strut rod nut is removed from the front of the K frame and the nut on the LCA pin is removed, and the t bar adjuster is backed all the way off, you should have enough slack to manage it w/o removing the lower bj from the lca. You might need to remove it from the spindle though. Try it 1st and see w/o doing anything to the lower BJ. I use a ball joint fork between the K frame and the LCA, works every time, no T bar tool needed. Ball joint fork works great too to pry a steering shaft coupler off a steering box input shaft spline. NOW IS THE TIME to replace the strut rod bushings and LCA bushings if they need it.

RapidRobert eluded to something big I discovered. If you put your car up on stands and your front suspension is hanging, the bars will actually torque the opposite way and load up enough to bind. By putting just the right amount of lift under the LCA, you get the bar unloaded to neutral and it comes out WAY easier.
I was on here asking for the same advice a couple months ago. I tried to remove the nut on the LCA and pound it rearward... Zero luck. Pry bar at the joint... Nope. I cut a piece of 20 gauge steel about 1" by 4", wrapped it in a U shape around the bar near the rear socket, grabbed it with vice grips and whacked it with a ball peen hammer. BOINK! came right out, no galling of the bar.
I’m listening.

I pulled of the UCA and the plate that it mounts to and dropped the shock in from the top. Even compressed they were about 1/2" too long. The stem kept getting stuck in the K-frame opening and couldn't get the bottom to quite clear the LCA. Good thing I was going to get the car re-aligned anyways because whatever alignment I had is gone out the window now!

Unless your alignment shop really knows how to work on old Mopars, I'd recommend YOU set the front end ride height. That's the 1st that needs to be done. Changing the ride height adjustment changes the alignment. Use the FSM method - measure off the bottom of the lbj grease fitting area and then off the bottom of the blade in the lca.
