I have a 1991 HDJ81 (RHD) and earlier this year I upgraded my suspension from stock to an OME (Old Man Emu) setup using new OME 850 springs in the front (and new OME shocks as well). The caster was obviously affected by this upgrade so I installed a set of bolt-on caster plates. The caster plates fixed the caster, but I have noticed that when going over a pothole, or a sudden bump, that there is a metallic 'banging' sound that is audible from the front passenger side (remember, this is a right hand drive vehicle). Upon closer inspection I noticed that the front passenger side coil spring has rub/wear marks from where the steel lip on the conical bump stop has been hitting it. The driver's side is just fine and there is no interference between the bumpstop and the coil spring. When you look at the passenger side conical bumpstop within the spring, you can tell that it is not centered within the spring, which makes me think the caster correction is to blame. I will say that the truck does not sit perfectly level (side to side) and the passenger side front is about 0.75 inches lower than the driver's side front wheel when measuring from the the center of the hub to the bottom of the fender.
What are my options for fixing this? I saw the following thread (see Bump stops hitting springs - https://forum.ih8mud.com/threads/bump-stops-hitting-springs.140904/ ) and wanted to know if any other 'Mudders out there had found a straightforward fix for this. I've seen everything from grinding the metal lip around the rubber bump stop to shimming the conical bump stop where it sits in the metal housing above it. Would an appropriately sized coil spacer (say 0.5 inch or 1 inch thick) help with fixing this issue? Any suggestions? Thanks!
