rock crawling question.

soronacrawler · 01-30-2007, 12:53 PM

For some reason every time when i start to crawl up the face of a rock, and im at very low rpms of course, i start to get this weird sound mixed with a lil shimmying that the jeep does before it begins to go up the rock.. i was wondering if anyone knows wat exactly is the problem.

im running stock gears, no locker, 33 mt's and a 5 inch lift....

Are you in 4Lo when doing your rock crawling? What axle ratio are you running with those 33" tires?

ya im in 4lo, and im running the stock gears that are fit for 30's.. im pretty sure its 3.73....

Well, you're a bit undergeared for 33" tires and rock crawling with your 3.73 ratio so that bit of noise is probably just a tad of extra strain on everything. 4.56 would be ideal for your 33" tires if your TJ has a manual transmission.

sounds like the vehicle is about to stall. more skinny pedal

(just a little bit)

the thing is you cant give it much skinny pedal at all if your articulating up rocks..... so im guessing ill just have to deal with it until i get new gears or every rock crawlers dream an ATLAS
