If you have 35's and wheel your 100 seriously, watch these two things: 1. Loosening front wheel bearings. 2. Worn out and/or leaking steering rack...and if you don't fix it ASAP it takes out the gear box (another $800). On a recent weekend trip my rack gave out and began leaking though the dust boot. The PS wheel loosened up in a matter of miles on a dirt road. We made it back to town just barely (5-hour drive). In 110K miles (80K with 35's) I've: 1. Found loose wheel bearings on 3 trips. One was CM05. They loosened up FAST. Tight one day and LOOSE a month later. Re-pack and re-tighten every 25K at least. This will be my 4th WB service/tightening. 2. Starting on my 3rd Steering Rack. The first one was swapped under warranty. It was OK, just loosening. This one leaked like a siv overnight. The front-end wheel wobbled and rattled over the bumps. I don't think there's any upgrades for this part. New ones are over $1000. The big tires and off-roading wear these out. I know some whacked out 80-dudes say I don't wheel my truck. My truck sure knows I wheel it. Any how.....KEEP UP ON THAT WB maintenance! We barely got home! So, $1500+ comes out of the account.
