Torque arm screws backing out?
Torque arm screws backing out? Since Ive installed my Moser 12bolt and my Spohn T/A I have had problems with the bolts backing out.
At first when I went to check on everything all 4 were a tad loose ( I red locktite'd every one of them). I figured that they just needed to get settled so I tightened them again.
They loosened a 2nd time so I re-locktite and re-tighten. The other day I raced a Lightning and *CLANG*, I lost the top bolt completely.
I replaced it and yet again I am having a problem with bolts loosening.
Is there something I can do? I sucks having to tighten them all up once every 3 weeks/handful of track passes.

I have to do the same to mine about once a month too. I have broke the cradle on the Spohn tq arm once before too from this. I just put them back in with some new lock washers, washers, and red loctite. I am going to see how this holds. If it doesn't then I am going to wire tighten them.
What are you torqueing the bolts to? I use red locktite and 100 ft lbs. I have never had mine come loose. You have to clean the bolts before using locktite.
Won't work on dirty or oily threads. I normally use Berryman's Chemtool or spray brake parts cleaner and blow dry with compressed air.
Good luck, Ed

I had my 12 bolt in my car for 2 years and the bolts attaching my spohn tq arm NEVER once loosened up... I read about this happening to alot of people, with different arms, different this and that, and the same thought runs thru my head every time, stop being a ***** and CRANK the damn things tight, and stop having problems. Get a god damn pry bar on there to tighten them if you have to! A little dab of blue loctite on mine and a set of lock washers and that was it.... 2 years, hard street miles, 20 launches or more at the track, nothing, no problems, no loose bolts, no problems.
I've read about people wiring them in, hell I've even heard of a guy tack welding the head of the bolt to the tq arm so it can't back out LOL.... stop using a 1/4 inch drive ratchet, get a good tool on there and put your back into it! Those bolts see more foreces then you want to know about, they're meant to, so tighten them accordingly!

JL is right. Also clean the powder coat off the mounting bracket before install on both sides.
Some have also found that some TA mounts are taller than the mounting bosses causing the tabs to bend down at an angle when tight. This causes reduced surface area for proper clamping forces. Putting a shim in between the boss and the tab to make the mating surfaces parallel can eliminate the loosening problem.
Been there, done that on a friends Formy with a BMR TA and DTS 12 bolt. Never came loose again.

We are running the Spohn Arm and the top mountintg plate cracked at the bolt hole.Called Spohn and they told me to put the relocation brackets for the LCA on to fix the problem. They also said to make sure the bolts had a wire saftey strap or to put a small tac weld on the bolt. Spohn said the 12 bolts have this problem and the 6 speed is more of a challenge to get right. There tech department is very helpful and is ready to help.

I've had the same problem, on a street/strip car. One day I noticed one bolt completely gone, and the second half way out.
I got new bolts, cleaned out the hole, used liberal amount of red locktite, and replaced both bolts, cranked them down as tight as I could get them. Waited a few days before moving the car, to let the lictite dry, and have since had no problems with those bolts. Wiring them would be a good idea.

yep. I made two thin shims and now it has never cam loose. The problem is all you do it put pressure on the mount bracket as it starts to bend. It doesn't bend enough to clamp the axle so the shim will take up that space. With the space when you launch the bracket flexes and the bolts loosen

I tried everything to fix this problem on my car, but didn't have any luck. It broke the bracket because of this, broke the torque arm too. I also tightened one of the bolts so hard that it snapped off in the rear end and I had to drill and tap it. I ended up fabbing up a bracket and welding it to the rear end. I now use all 8 bolts instead of just 4.
Before I did this I ran two long bolts through the extra 4 holes and cranked those down with great results. I think this helps clamp the bracket together better. Hope this helps, Brian
