  1. I put muself down on my knees with a camera many times to look underneeth of LJ's and LT's and was every time surprized by seeing almost different spring hangers, side step brackets and so on on LT's. It looked like someone rebuilt them with newer or different truck's components but to the moment I met no exception.

    The early trucks, all 3 axle had a different frame design than the later trucks,(LTSW.LTLSW,LTLT,LTHSW, LTHT? don't think there was one. The difference is the web tapers up starting behind the front rear spring hangers and the later trucks the taper starts between the front hangers. The steering shaft passes below the flange, I have one and seen others with a factory inside channel from over the center of axle back to the about 3' past the rear hanger, and the rear hangers are unique to this design.

    From what I have seen and recorded at least 200 units were built this way ,assuming all LTSW's. The later design, taper over the axle, is on LTSW # 1482 has it , and all LTLSW's, and LTLT's. LTSW's had either 1/4" or 5/16" frames, I believe all LTH's had 5/16", and LTL's 1/4".

    All trucks have the same front spring hangers ( steel or aluminum depending on the model), the rear hangers on the early (steel), different from the later (steel, aluminum), and the LTH's have (steel) and I have seen some shorter in height.

    All trucks have the same length springs, different number of leaves 12/14 depending model and mfg of spring.

    I have been looking at and under every LT for the past 26 years gathering information etc., but still find something new and different.

  2. Ok guys- my frustration level goes up. Screwed around with this some more and 1/2" is best I can get. have space between clamps and spoke so that is not an issue. One thing I see, when I look at inner rim, the inner bevel edge on one of the spokes does NOT make contact anywhere with the angled edge of the rim.

    My next move is to flip the inner with the outer wheel and see what that does. By the way I've had more than one experienced guy tell me..."1/2"? forget about it-" I do use the truck, not uncommon to hit 38,000 lbs (its a single axle) but I'm always on rural/secondary state roads.

    There is a difference in the inside diameter between the 8 x 24 and the 8.5 x 24 rims, the 8.5 is smaller. Most all of the heavy single axle 24' spokes were set up for 12 x 24 tires and 8.5 rims. 8" rims will be loose on the rear spokes and 8.5" rims will not seat properly on the front spoke . FA 600,601

  3. what do they mean when they say is it a westcoast R700 what is different someone said front axle???

    The western trucks have the straight frames of standard width (34"?) to accommodate vendor suspensions and axles, My RS has Mack engine, trans and rears on Hendrickson block and Rockwell front axle.
