hogelectra Posted January 21, 2009 Share Posted January 21, 2009 Ok did a 2" lift front and 1 1/2" back on my MJ. I used my factor rims and put Mud 30x9.5 on. Lots of room upfront ny chance of it ever rubbing. But when I went out and did some simple trail rides - testing suspension for travel and rubbing - and when I got back I was surprise to see rubbing on the truck box at the top where the tires rubbed. That was a shock to me http://www.comancheclub.com/forums/post ... =post&f=2# What should I do? http://www.comancheclub.com/forums/post ... =post&f=2# Link to comment Share on other sites More sharing options...
BLHTAZ Posted January 21, 2009 Share Posted January 21, 2009 Don't know what you tried to link there, but neither of them work. As for the truck...it sounds like you need some extended bump stops. Link to comment Share on other sites More sharing options...
hogelectra Posted January 21, 2009 Author Share Posted January 21, 2009 That makes sense or do I need rims with less backspacing Link to comment Share on other sites More sharing options...
BLHTAZ Posted January 21, 2009 Share Posted January 21, 2009 Less BS would push then out further and you don't want to pull them in any more as the rears are already tucked in more than the front. Link to comment Share on other sites More sharing options...
Pete M Posted January 21, 2009 Share Posted January 21, 2009 What rims do you have now? And are the bumpstops still on the truck? How did you lift the rear? Link to comment Share on other sites More sharing options...
hogelectra Posted January 21, 2009 Author Share Posted January 21, 2009 They were stock steel rims off of a 86 cherokee - 7 inch The rear was lifted with add a leafspring. The bumpstop is still on. I was thinking of placing a 2" spacer between the frame and the bumpstop to lower it back down to account for the lift Link to comment Share on other sites More sharing options...
Pete M Posted January 21, 2009 Share Posted January 21, 2009 Or, you could add steel to the axle side. I don't trust those bumpstop bolts. I snapped off 3 of the 4 on my truck. :( Link to comment Share on other sites More sharing options...
hogelectra Posted January 21, 2009 Author Share Posted January 21, 2009 You know everytime I go out to do some rock climbing and off-road I look for mud so I can have this nice dirty truck to post a picture of - but you know here in the desert finding a big enough mud hole is almost impossible. Would the new steel buildup on the axle have to be solid or could a fabricate a steel box from 3/16" and mount that Link to comment Share on other sites More sharing options...
pingpong Posted January 21, 2009 Share Posted January 21, 2009 I had the same issue on Pong when Pong was less modified. When rubbed on the frame.. so I went out and bought a set of spacers.. and it fixed the problem. This was back when Pong was running 3ox9.5 on no lift though Link to comment Share on other sites More sharing options...
Pete M Posted January 21, 2009 Share Posted January 21, 2009 Would the new steel buildup on the axle have to be solid or could a fabricate a steel box from 3/16" and mount that 3/16" material should work great. :thumbsup: Link to comment Share on other sites More sharing options...
Eagle Posted January 22, 2009 Share Posted January 22, 2009 Bump stops are not the problem. There is very little clearance betwen the inner wall of the tires and the fender at the rear of an MJ. When the suspension articulates (one side extended, the other side compressed), the tires tip, and the inside of the "stuffed" tire rubs the sheet metal. The solution is rims with less backspacing (which then creates other problems in the front), or spacers in the rear. Link to comment Share on other sites More sharing options...
biggwheels Posted January 22, 2009 Share Posted January 22, 2009 IMO i would be getting some longer U-bolts for your SOA and weld those spring perches . better be safe then sorry ... Link to comment Share on other sites More sharing options...
Pete M Posted January 22, 2009 Share Posted January 22, 2009 Don't worry. That shot was taken during mock-up. :thumbsup: Link to comment Share on other sites More sharing options...
mvusse Posted January 22, 2009 Share Posted January 22, 2009 I had a problem with my 235/75R15s on 15x7 stock rims hitting the inside of the rear wheel wells under flex. Both with stock rear suspension and with 4.5" lift. Those tires are pretty much equivalent to 30x9.50. Fixed mine with 1.5" spacers. Link to comment Share on other sites More sharing options...
JOMJ87 Posted January 22, 2009 Share Posted January 22, 2009 Let me try to see if i read write. You are rubbing on your bed wheel well on the inside of the tire? Mine does this and i have a shiny spot from rock crawling. Theres not anything to tear the tire so i havent worried with it. You would want less backspacing if this is the case. Here is a pic is yours rubbing where my shiny spot is its a old pic so it bigger and brighter now. :D (the only thing close to chrome on the truck) Cole Link to comment Share on other sites More sharing options...
hogelectra Posted January 25, 2009 Author Share Posted January 25, 2009 rear spacer has solved the problem - now to check them regularly to make sure they stay tight Link to comment Share on other sites More sharing options...
