    Well I had a problem with the first run of the LR UCA's, well actually 2 problems, that SPC took great care in resolving!

    But the issue I was not satisfied with is the rubber bushings. The first run had the wrong rubber durometer. They updated it and sent me replacement set. The defective set I figured I try and modify to my liking.

    This is what I have so far:

    This is what the bushings originally looked like:
    [​IMG]


    This is what I did. Removed the defective bushing, and bead blasted the entire UCA's:
    [​IMG]


    Then I had to Fab up some DOM tubing and poly bushings:
    ((Note! No place makes a set that would fit off the shelf))

    Now I'm in the process of drilling and tapping them for some 90* zerk grease fittings:

    [​IMG]

    The thread size is 1/4 28:

    After I do that I'll paint them and put them together.
    I should have time today to paint them!

    Awesome! can't wait to see the finished product. did you make the poly bushings as well, or are they store bought.

    Nice! You may want to cut small groves into the bushing were the sleve goes, so the grease will flow to the ends.

    The poly bushings I got from "Energy Suspension" But the were oversized. I need to cut them down to fit.

    I was thinking about doing that, but I'm not sure if it's necessary? TC's don't have any groves. I still might do that. But I have extra sets of self lubricating bushings, I might try those for the next set I make.

    You know I might make a few extra bushings, if I have the time? But the hardest part about this whole thing was removing the old rubber bushing. Big PITA!!
    If I do make extra bushings I'll let you guys know, but you'll need to do the install yourself. (Unless you pay to fly me up there!:D)

    All the TC's I have installed had channels that allowed for the grease to flow to the ends of the bushings...

    Really? That must be something new? When I had mine the bushings weren't grooved. I need to machine it down a bit more, so I guess I'll groove it then.;)

    So, what was the real problem with the LR UCA's that you're trying to fix? I've got them and just want to know if there's something I should look out for, or look into doing this mod on them....

    The first batch of LR UCA's had 2 problems. (I found them both) And notified the company.
    1- the Ball joint was defective and didn't have the full range of motion.
    2- the durometer of the rubber used in their bushing were wrong. The rubber was tearing/failing.

    SPC was very helpful with both issues. Customer service is awesome!

    You need to look at the conical side of the bushings. If they are tearing from the inner tubing then its the old rubber compound. the new set I have on my truck is holding well. So far no issues with the new compound.
    They fixed the problem about 2 yrs ago, a few months after they introduced the UCA's.
    I had these sitting in my shop for well over a year. If you purchased your set recently they should be good!

    sounds good. I got them like a year ago so I should be fine, but I'll take a look anyway. I've been getting a clunking from my passenger front suspension that I havent been able to figure out, maybe i'll get lucky and this will be it.

    How are the LR UCAs? Thinking about getting a set soon so I can go up to 2.5" on my 5100's.. Nicer price than the TCs.

    The LR's are a good option! They have one thing you need to keep an eye on. The adjuster nut could move at some point of high stress.

    But to make it easy on yourself. When they set the alignment, have them set it all the way out. That way if it ever moves you can return it to it original position without an alignment!;)

    Nothing wrong with mine, I just like the idea of having them bead blasted and then re-powder coated another color. :D

    O.K. I'm a Dumbass! It occured to me last night, that these bushing won't work!:frusty:

    The part that I need to replace is the bushing tube! I need to cut off the existing tube and install a larger tube!:annoyed:

    Oh well? I wasted a few hours, now it's back to the drawing board!

    I might as well change the geometry of these to improve the design while I'm at it. I need to set up a jig for it. This should be a great R&D project.:D

    It actually occured to me in my sleep that the LR rubber bushing stick further out than these bushing. So to make them fit on the truck I actually need a wider tube not a narrow bushing. So I modified the wrong part.

    Good thing I have extra parts laying around my shop!:p
