Thanks, Toasty. Agreed.

My welding skills are below average at best, but I do have a small Mig and should be able to handle this.

I spent much of today with a grinder getting things cleaned up. Cutting them off the parts car without destroying them is proving to be a PITA so I may just re-weld my originals if I run out of patience.

The mystery is solved.

I went ahead and got my parts car in the air and tore down the trailing arms. As I feared, what I was calling "inner washers" are welded to the frame bracket which retains the front of the arm and bushings. It explains why they don't show up in any parts catalog. On my Montero the welds rusted out and they came off entirely. They have nothing to do with adding strength to the bracket, but they do appear to be pretty important for maintaining lateral location for the bushings / front of the trailing arm. See pictures below.

At this point I don't see a good option other than cutting them off the parts car and welding welding them on to my driver. Anyone have a better idea? I'll probably post on the Montero USA FB page for ideas and if anyone is interested. I appreciate the responses to my original post and hope this may help anyone else who runs into the same issue.

Thanks very much. I'll give that a try for the "inner washers" (or whatever they're properly called).

Any thoughts on whether the trailing arm shaft wear means they should be replaced as well?

I'm the proud second owner of a 1994 LS 5-speed that I acquired with 177k on her earlier this year. I really wanted a manual transmission (personal preference), it's got beautiful paint, a beautiful interior, and is about as straight as a 23 year old truck can be. Other than the anemic 3.0L (to be dealt with in future) and the list of ADD goodies, etc to be installed over time, I'm loving it. Before I got it the truck spent most of its life in California then Arizona, but unfortunately it also spent the first 4 years (or so) of its life in Wisconsin. While most of the rust is cosmetic / non-structural (and would be considered next to nothing in salty climates), there are cases where it's already being a PITA.

One of those is the rear trailing arms.One of the front trailing arm bushings gave its last gasp earlier in the week and I set about replacing it yesterday. While I was in there I figured I might as well do both sides. One of the receipts I got with the truck showed the rear bushings having been replaced recently, so I wasn't worried about those. Other than a sway bar mount bolt that snapped off and had to be drilled out and re-tapped (another rust PITA), it was all straight forward to pull apart. And now I have two problems:

1. There's a fair amount of wear / erosion on the front of the arm where the bushings mount. The shaft is noticeably roughened and reduced in diameter at the center.

QUESTION: Is this common or uncommon on these trucks? Do people sleeve them, weld them, replace them, or just say "no big deal" and put it back together with new bushings?

2. What I am calling the "inner washers" are all but eaten away. I have scoured the internet, looked at every parts diagram I can find, and done every search variation I can think of but am finding neither part numbers nor other references to them. And maybe I'm just being an idiot and missing something completely? I have the 1994 FSM and they're not even shown as separate parts (section 34-4 upper diagram). From front to rear there is: Thick metal washer - Bushing- "Inner washer" (not shown in diagram) - frame bracket - another "inner washer" - bushing - Thick Metal washer - lock washer - nut.

QUESTION(S): I had picked up a set of MOOG bushings (rubber bushing only), but maybe the "washers" come with the OEM Bushings (MB809388)? Or the "inner washers" are actually supposed to be welded to the frame bracket and rusted off? Or something else entirely?

I do have a parts truck (SR with locking diff) but won't be ready / able to strip it for at least a couple of months. Upgrading to ADD Siberian bushings is part of the plan when I start swapping axles which is why I went "cheap" with MOOG for now.

Any words of wisdom, part numbers, source for good used ones, or setting me straight on what I may be missing would all be greatly appreciated!
