So i have a 97 2.5L 5 spd right now. I run 4 inch lift on 33's but after these tires wear down i wanna go up to 35's. So what exactly do i need to do in order to safely do this.

Start reading the forums about what is needed for 35s. some of the things you WILL NEED to upgrade are: brakes, steering, axles. unless you don't wheel your jeep and its a street drivn rig then you might be able to get by with bigger brakes. It really depends on how you drive it and if you wheel it and what kinda trails you wheel.

Mud doesn't put much strain unless you really put the petal to the metal and turn your tires like there's no tomorrow. Just have fun in the mud, and if you see your self slowly sinking or trying to get through deeper stuff, don't crank the steering wheel back and forth, just try your best to get out using the least amount of force possible. Your better off stuck than stuck with a broken axel.

You NEED to Regear, upgrade brakes, and upgrade your rear axle for 35" tires unless you only drive on road (in that case, cross off the rear axle) A 4banger with stock gearing will be horrible on the highway with 35" tires. Stock brakes need to be upgraded to either high performance rotors and brakes like Black Magic or a whole new brake kit that will upgrade the calipers as well. The Dana 35 would be pretty scary on 35" tires with no upgrades, most agree 33" with gentle throttle is the max. If you are in the mud where you are spinning the tires fast and may suddenly grab traction, your axles will be taking lots of stress.

If I were you I would stay with 33" tires and use the money saved on brakes and a Regear to either upgrade the Dana 35 with a Super 35 kit or replace it with a Dana 44 or ford 8.8 with a locker. A locked rear end will make a huge difference offroad when you are used to an open differential or LSD.

Exactly the opposite. The addition of a front locker is the tipping point where the D30 needs to be beefed up.
