About 20 years ago I did a mini-truck/FJ60/4-Runner disc brake conversion on my '71 FJ40 front axle (mini-truck knuckles/steering arms/spindles/Birfields, FJ60 vented rotors, and 4-Runner IFS calipers). I reused the FJ40 tie rod, installed new FJ40 TREs, and fabricated tapered bushings to fit the TREs into the mini-truck steering arms.
I now (finally) plan on upgrading the tie rod using a spare FJ60 tie rod I've been storing since then. Back then I was unable to source a left-hand thread 23mm tap, so I put off the project. Now that I have a couple of sets of 23mm weld-in TRE inserts (thanks @lcwizard) and new 23mm 555 brand TREs, I'm ready to start.
I'm thinking of retaining the passenger side (LH thread) end of the FJ60 tie rod as-is, cutting the other end short, and welding in the RH thread TRE insert on the drivers side. That way I only have to make one weld on the tie rod.
Questions:
1. Can I use the weld-in TRE insert in the FJ60 tie rod? I trial fit one of the inserts in the tie rod, but it was within the slotted/threaded area, which will be cut off. It seems like there may still be a small amount of slop - the OD of the insert is slightly smaller than the ID of the tie rod.
2. I won't be doing a lot of hard core rock crawling, and will be running tall/skinny 33X9.50R15s or 235/85R16s. Is there any need to upgrade further to 1.25 OD X 0.25 wall thickness DOM tube?
