my 98 4runner 4WD is quickly approaching 200k. i have OME 906/881 with a 1" spacer in the back. I needed the spacer to level everything out after the spring upgrade, as I only rock a 2.7 4 cylinder. When i get some stuff or passengers in the back, i get a clunk/rattle from the rear. It looks like to me that the exhaust is hitting the body- like the body mount bushings are collasped, allowing the exhaust to hit. I've been looking around, but haven't found a clear-cut answer. I'm thinking of replacing the body mount bushings, but have some concerns about the body mount bolts. Do the bolts have issues coming out?

I'm thinking of upgrading to the poly bushings- where is the best place to get them?

 

spray them down real good with PB blaster - only place i know of right off hand is www.4crawler.com for the mounts
