flint54 Posted February 18, 2011 Share Posted February 18, 2011 Since owning this truck, I've always noticed the LH rear is lower than the RH rear, and I've always attributed this to a sagged spring on the heavy side (fuel tank and driver). Now that I've installed new HellCreek Metric Ton springs, the difference remains the same. I'm measuring fixed frame point on each side, to the ground. The LH side is 3/4" lower then the RH side - still. I know with certainty this truck has never been damaged, and has never seen anything more challenging than the occasional speed bump or pot hole. Why, I wonder, is this so far out from spec?? FSM body point diagram indicates less than 1/8" maximum deviation LH to RH. Any ideas? Link to comment Share on other sites More sharing options...
mvusse Posted February 18, 2011 Share Posted February 18, 2011 Try swapping your front springs side to side. Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 18, 2011 Share Posted February 18, 2011 Or replace them with OME coils. They are marked R & L and will level you out. Link to comment Share on other sites More sharing options...
flint54 Posted February 19, 2011 Author Share Posted February 19, 2011 Hmmm. I puzzled how the front springs would affect a frame to ground height difference measured at the leaf spring rear attach point? The front is level side to side. I may still be changing the front springs soon, but that will come with the front axle assembly replacement (one end at a time). After the 3.55, Chrysler 8.25, locker, MT2200 spring, disc brake, rear mod is done (another week or so) I'll tackle the front. I'll look into the OME coils, as I'm a bit leery of adding any more spacers beyond the one already in place. Link to comment Share on other sites More sharing options...
Pete M Posted February 19, 2011 Share Posted February 19, 2011 I wouldn't go too nuts over it. I remember a guy a couple years back that had a slight height difference. he went to the extent of swapping the springs left to right and got no change what-so-ever. :dunno: Link to comment Share on other sites More sharing options...
Dave Stark Posted February 19, 2011 Share Posted February 19, 2011 Are you performing these measurements with a full tank of fuel? Remember the gas tank is on the drivers side & that could affect it a bit... Link to comment Share on other sites More sharing options...
flint54 Posted February 19, 2011 Author Share Posted February 19, 2011 Pete, I know I probably shouldn't worry about it, but my symmetrical mind is struggling. :D The tank is at about 1/2 full, so I figure about 57lbs of fuel (18.5/2*6.2), and the spring rate of new MT2200 is 130lb/in, so the fuel should account for 7/16" delta. I feel much better now - thanks!! :D Link to comment Share on other sites More sharing options...
flint54 Posted August 25, 2011 Author Share Posted August 25, 2011 Just to close this old loop, I now have a set of OME coils, marked "A" and "B" (for LH and RH) and they solved this trivial issue perfectly! Link to comment Share on other sites More sharing options...
