Is something going to break....

I have a 2000 (xj) with a dana 35 and the np242. I'm putting a 3.5" RE super-ride on it with 31s. I tend to tow a pair of jetskis (~2000 lb. trailer) and pack 5 or 6 in the jeep for jaunts to the lake, is this going to put too much strain on anything.

Basically, I am not too familiar with what causes axles to break or t-cases to explode, but I see a lot of it on the forum. Should I be worried at all, or what can I do to prevent either of these things breaking?

My xj has about 55k miles on it so it's decently new and I don't do any extreme offroading, just here and there getting around.

You will be fine. I have flat towed a sami and i have 4.5 and 31's and i was loaded down with gear. Also have 155k on it. You should have no problem.

You should be just fine.

only problem is you COULD be lacking of power from not regearing, otherwise you should get by just fine

You'll be fine. Axle breakage happens when you're going over rocks, up very steep slopes, etc etc with larger tires on a d35. Just make sure you change your diff fluid, a lot of people don't and it wears the gears and bearings faster.

The only possible weak point is the D35 but if you drive smoothly you should be O.K. If you want real peace of mind you can put in a junkyard 8.25 or D44 and not have any worries.

how often do most people that DD their xj's change the diff fluid?

98xjjeeper · Aug 20, 2009

I try to change it every other oil change and before a long trip and after a really muddy weekend lol.

For a street driven XJ, once a year is adequate. If you tow regularly then you can change it more often. If you put a super strong magnet inside the rear diff cover then you can extend the oil change interval to one year or more.

Don't forget to change the transfer case fuild every once in a while. Thats probably the most forgotten fluid.

^ this. When I worked at a quicklube you would be surprised how horrible the fluid we usually drained out of transfer cases was. Chunky, completely the wrong color, etc... usually not very much left either.

Tranny cooler if it's an automatic.
