Default Installing trailing arm bolt tips

Figured I would throw this out there even though I’m sure some of you already know this. In short I just reinstalled the trailing arms after having them gone through. First off they are more awkward than heavy. I did it on my back, on jack stands, with no help but getting help wouldn’t be a bad idea. Rigging up a support stand of sorts to hold the trailing arm wouldn’t be a bad idea because they want to roll given all the weight is on the end. Two items that I consider almost essential is a set of small long nose vice grips like these https://www.irwin.com/tools/locking-...th-wire-cutter and a decent pry bar.

Because the area getting the bolt into is so tight what I did was lock the pliers onto the bolt about 1/2” up from the threads. The closer to the head of the bolt you can get the better but you have to have room to get the bolt and plier combo in there. Then stick the bolt into the bolt hole so it sticks out a 1/2” or so into the trailing arm pocket. You want to leave enough room form the trailing arm to move past. The pliers basically give you longer fingers and if you have large hands like myself getting your digits up in there is challenging. Then slide the trailing arm into the pocket with it all the way to the outside to clear the bolt. Here’s where it gets tricky if you are by yourself without a buddy or a fixture. You will have to lift the arm up, line up the bushing hole with the bolt, and using the pliers slide the bolt into the bushing as far as you can until the pliers bottom out on the frame. Once you get the bolt in 1/2” or so it should hold it and you can adjust your game plan. Then pop off your pliers and grab your pry bar and gently work the bolt further in while lifting and turning the trailing arm to hopefully align it. Once you get it to the end you might need a wrench to turn it and thread it into the other bolt hole but that isn’t too bad. and then push it past and up onto the bolt nub you have sticking into the pocket.

Once I figured out the vice grip trick I had both arms in in 30 minutes, but I spent about an hour at first just trying to get that first bolt started. Hopefully this helps somebody out.

I installed mine solo also. I did basically the same thing but used long nose pliers. The most important tool is patience.

I did in a few minutes on both of my cars. Best to start with an arm that does not have a caliper or rotor on it. I put a piece of wire through the frame pocket and the training arm and attached a piece of dental floss to the bolt and the wire. I pulled the wire and floss through and the bolt followed. It is easier to line up the trailing arm in the pocket on an arm that is not too heavy and lopsided with the caliper and rotor attached. Jerry
