Invest in an axle swap?

Iím looking into regearing my axles on my 2.5L 5speed YJ with the D30/D35 combo, but have been thinking about investing in a stronger rear axle like a 8.8 or D44, I donít plan on wheeling it too hard, so itís going to be my daily driver. Should I still invest in a new axle and then do new gears? Or keep the D35 and regear that?

If you are not going to wheel it you dont need anything stronger than the turdyfive especially with the 2.5. If you actually wheeled the jeep the 8.8 would be a cheap option for an upgrade.

I did the 8.8/rebuilt d30 axle swap and it has been a lifesaver for my 93 YJ. It was crazy to drive because of prior owners doing crappy work and now it is solid as a rock. I got lucky and found a fellow jeeper who works at a Jeep shop that was selling his front and rear to switch to Rubicon axles. It was already set up for a RE 4.5" lift so all I had to do was remove and replace. I do think I need to have my rear shock mounts adjusted and rewelded onto the axle. They seem a little short.

Agreed...

Gearing depends on tire size you plan on running.

The original post says he isn't going the wheel it "too hard"... lol. We all know how that goes. Take this opportunity to upgrade that rear axle.

I used the same driveshaft that came in it when I purchased the Jeep. It already had the double cardon end and the slip in the middle. The guy I got my axles from gave me a Tom Woods drive shaft but for some reason it was too long to go in. I'll gladly sell it if it works for someone else. I had 4Wheel Parts do an alignment on it once we got done and it drives nice and straight. I have a little vibration up around 65 or so but I think it's in the tires.

Dude I've wheeled the absolute piss out of a 4.0 5-speed YJ on 33s with a stock Dana 35 under it since 2007

Avoid being the dumbass that floors it when it stops moving forward and makes it bounce and you can do a LOT of wheeling w a 35

So a d30/d35 with 5.13 is good enough for daily driving? 2.5L 5speed 33s

Absolutely...

Now add a locker and make poor decisions offroad and you CAN break it but I regularly bark tires on pavement on a 1-2 shift w 33's and my 30/35...

Yes... 5.13's is a great choice with 2.5, 5 spd, and 33's
