Being on here for a couple of months I've noticed that there's a lot of focus on strengthening the rear axle. A lot of dislike for the D35 and preference for C8.25, D44, etc. I'm thrilled to find out that my XJ has a C8.25 in the rear, but I'm not sure why... It makes sense to me that a good rear axle is important for towing or highway travel when you're in 2H a lot, but what does it have to do with offroading when you're in 4x4 mode all the time? How come nobody upgrades their front axles? Isn't front strength important when you're relying on the front wheels to haul you over obstacles? Is the Dana 30 just inherently better and most rears suck the big one, or is there no other option?

i have a 99 classic with the 4.0 in it. 82k miles on the motor and tranny etc. have an aritex fuel pump in it and i seem to be losing fuel pressure? i can crank up. and drive it no problem but maybe 20 seconds later it starts to sputter and bog/stall like it has no fuel getting to it. i pop it in Neutral, cut it of, crank it back up (all while rolling down the road) and when i put it in drive and stomp the gas i have all the power again for the same ammount of time sometimes its not too bad sometimes i have to start it every 100 yards to keep it running. any help would be greatly appreciated. i can easily replace the fuel pump but that would make this my 3rd one and its getting to be a bit expensive and i was wondering if there were any other routes to take?

Does anyone have an opinion on the OEM side rails/sliders Jeep offered as an option? Jeep calls them "rock rails". But, I know they're a bolt together application. At the same time, they're much cheaper than any aftermarket option. Are they worth a darn?
