Your Jeep has a part time 4wd system, meaning that when you pull that lever into 4wd, its in 4wd until you move it out. There's no computer control etc, its a solid lock between your axles/transfer case. Driving around on the street in anything but 2HI will smoke your transfer case and just about every moving part on your 4wd system. Only use 4HI or LO in situations that you actually need them in. Take a look at the your owners manual or do a search on here on how to use your 4wd system, I'm sure more people will chime in here as well. But once again, driving on the dry street in anything but 2HI WILL destroy your 4wd system no if ands or buts about it. If you've been doing this get out of the habit now.

Ok cool just wanted to make sure cause I've been running on 2hi but maybe I thought the axles need more help with bigger tires.

Thanks though

Not a problem, glad to help you out. What ratio are your axles? With that much lift and 33s you would definitely want a more aggressive axle ratio to help turn those tires easier. Do you have an auto or a manual?

it's called regearing. you have a shop install a deeper gear ratio in both axles, depending on what transmission you have.

for 33" tires, if you have a NV3550 manual you install 4.56 gears. if you have a 42RLE auto, you install 4.88 gears.
