Gen 1 trailing arms?
« on: September 29, 2018, 03:07:07 PM »
I've seen references to the need for upgrading Gen 1 trailing arms, but I've also seen vague references to only being a concern with the LWB/v6.

Is this necessary on my 2.6l SWB? Is this something that needs to be fabbed or is there a bolt-in?

Your SWB is V6, right? All the same tech applies. Use Gen 2 arms and rear axle.

2.6 SWBs don't have trailing arms so no worries.

Did I read somewhere that there was a place(lower edge somewhere) that a reinforcement could welded on the Gen 1 arms.

Yet another reason the 2.6l rules!  ;)

Doug, I had Ray's Montero "Ole Blue" that arrived with the 'modified' Gen 1 rear arms. The modification had 1/4" strapping welded over the flex point failure locations. They were done, the straps fractured and shot.

Is breakage of the Gen 1 trailing arms mostly just occurring with those who have removed their rear sway bar?

The arms are just really thin, any wheeling is going to break them eventually. I even bought a truck that hadn't been offroad and it had a broken arm, that's why they revised the part. They are almost exactly the same on the gen 2 except they run a smaller bushing making the sreas around thicker. As far as reinforcing them goes, it could be done but you'd need to remove the bushings, preheat the arms, weld extra plates on the bottom with a structural weld process, post heat then dress and polish all welds. Even after all that they could still break on the top sides. In short just get gen 2 arms.

Will any Gen 2 arms work?  Any advantages to SR ones?  I just know to use the Gen 1 bushings on the front.

I might go pull some tomorrow.

This from a SWB V6 89 that I broke then up graded to the Gen 2. No problems since and love the Siberian bushings. I had the rear sway bar on when they broke but off now with the new Gen 2 arms. Welded one at bottom is not mine donated from the wire back when by one of the mods.

Ok, looking at your side by side I dont see any real advantages to the 2nd gen. If anything the material around the circumference of the bushings appears to have even less material. Is it really even an upgrade. I ask because I have a 95SR that Im pulling parts off of and was going to grab these as well, but now im not so sure. Interested in why these appear to be a better choice.

There is more beef to them it just doesn't look like it because the Siberian bushings have a lip on the outside where the original bushings fit flush inside the arm with no lip on the outside.
