LM Rear Trailing Arm Bushing Question confused smiley
Posted by: Mike J ()

Okay, I noticed this yesterday when I was getting ready to "fit" my wheels now that the exhaust is on.

Holy crap !!! the passenger side trailing arm bushing seems to have "slipped out" a bit. So, I should unbolt that one and drop it down and try to "re-set it" with like a giant C clamp and a socket? I'm really not in the mood to pull that whole side again.

Also looks like a brake line leak? I'd better tighten that one up again and see.

Suggestions?

What's up Mike ? I experienced a similar problem with the bushing, somehow the hole in the A-arm was worn out, so the bushing came out. The only way I was able to fix it was by replacing the whole arm, yep, I had to pull the whole side to replace the arm. Some guys will take a short cut, by pushing the bushing back on and welding around it, myself I won't do that......maybe in your case , the bushing was not pressed in all the way, maybe try to push it in and see what happens......and I would definitely tighten that brake line, or you will be doing the Flinstones to stop.....don't sweat it , man, it looks easier than you think.... so fix it, and keep it rolling, peace out.

Thanks Raff~

Now you have me thinking. I guess I'll try and see if it will go back in. The shop that pressed them in said it took quite a bit to get them in, but what does he know? gggg

Oh well. Thanks for the info ... once I'm done at dad's place it will be time to tackle this one .. again. Still need it ready by the end of the month to work out the bugs for the Spring Fling.

Yup, it happens.

Welding is an option, and could be done in place (not all the way around of course)

Another option is to tap a couple of holes through the arm and bushing (which is metal sleeved) and bolt them together.

There really isn't going to be a lot of force side to side on those bushings so it doesn't have to be super strong. Besides, I am sure there is still some grip from the press fit.

Mike J, I would advise you to pry/squeeze it back in place and mig a spot from the arm to those bumps on the bushing shell. Nothing wrong with a short-cut if its safe, permanent and saves you a lot of work. Maybe the bushing where a tight fit,but a shop will often tell you the job was tough to do--just to justify the charges .

I think just a tack weld or two (or three) would do the trick just fine once it's back in place.

Right on guys. Thanks for the confirmation of a good short cut. I guess I'll try to drop the front mount, press it back in and tack it in a couple of spots. I'm sure it will be secure and safe on this street car.

Ya just hate to see something like this when you are this far along in the build. It must have pulled out as I was tightening the arms in place? Or the side rods? Well, they don't have much pressure on anything. I'm sure it's something I did during the assembly. Oh well. Live & learn.

Next time I'll do the down to a shell thing like you hard core guys and make sure the whole car is perfect.

I had the same thing happen to me. Installed the 90 durometer ones (the stiffest ones that Walls had, blue in color). Noticed later that they had done just what yours did. I thought it was because they were so stiff and the alignment shop had done a crappy job. I pulled one of them back in and tried tack welding it. Whoops, that material will catch on fire! So then what happened is the shell stayed put (since I tacked welded it), but the busing material pulled out then.
I ended up pulling it all apart again and went with the 75 durometer ones, only I installed them with some of that Loctite press fit repair stuff. Had it realigned and they have stayed put ever since then. That was about 5 years ago.
Take it for what it is worth... Maybe you can get away with just tacking it and it won't fry like mine did.

BTW, I have one 90 durometer bushing in good shape and one slightly charred one if anybody is interested. winking smiley

Ha Greg ... HELP! No, I think this will be a one day thing. I might try epoxy on mine? No welder around to tack them, but I've got some good epoxy laying around somewhere. I'll just put it on the back side ... as if I was tack welding. Just in 2-3 spots?

Brad ... thanks for the advise. I don't want to burn anything up, with my luck the who car would go up in flames. gggg But thanks for the advise.

Mike, I noticed that in the second photo, the bolts in the mounting bracket are not centered in the slots like they are in the first photo. You can see where the bolts USED to be by the marks they left. It looks like that bracket is farther OUT than it used to be and the new position corresponds with the direction and amount of drift you have...

Mike. Take the bolt out, get the arm where you can work it, get some washers.

After you have the bushing back in place drill three hole into both and then tap and or self tapping screw.

I bad now so it should pull together easy and the three bolt and or self tappers will make it work. I have an arm here.

Luke, that was one of my concerns for when I get the alignment done. It doesn't seem to go back where it once was ... probably due to the bushing coming out?

Jim, I'll see what I can do with it once I press the bushing back in place. I'm either going to put a little epoxy on the back side to hold it in place or ???

Aaron, thanks for the compiment. It was a lot of hard work doing all that. It's the result of one of those "while it's out I'll just clean it up a bit" statements. I dropped the power pak to replace the 2 tranny mounts ... ha ha ha.

Greg, Yeah, if I ever do another Corvair build, I'm afraid it would take too long to complete it. You are correct with that statement. lol.

Spread some of the Loctite press fit stuff on it and set screw it in place. You can probably get two good ones in without even dropping the mount, 4 if you drop it. You could probably even use roll pins (which you could bondo and paint over) if you want it to look a bit more stock.

Try hitting it with a rubber mallet put it back in place (don't worry if it goes in with a mallet, it will come out so you can put the locktite on it).

>> It doesn't seem to go back where it once was<<
You do remember that the inboard "L" brackets on the stabilizer rods have slots for adjustment. Those bolts should be loosened again for the alignment. You shouldn't tighten suspension bolts without the weight of the car on the wheels when you have rubber bushings. You can put jack stands under the rear of the trailing arm, then tighten the stabilizer bracket and trailing arm bolt.

why is it a short cut to weld the bushing in? a few tack beads w/a mig id think would be a 100% acceptable/good repair. whats your take on this rafman - why do ya think its a short cut?

Ah, put the jack stands under the wheels - load bearing weight for adjustments & to tighten the suspension? Man, I need to read a book or something.

Thanks Richard. I'll loosen everything again on that side to fix this one and then when it's right, I'll loosen everhting on both sides again - lift the cars suspension to be load bearing .. and then tighten everything?

Looks like I've got a few more things to do then I thought. ggg
