The SJ is 4500-5000+ lbs. The ZJ is like 3500. The SJ makes more power than the 4.0 ZJ...no coil springs or anything. More weight=more wear, right?

Of course, there's always the "It's a Wagoneer; it always needs something" argument too 😉

There are 2 major differences between new Wranglers and FSJs. FSJs are meant to be both utilitarian and capable, not just capable. FSJs are also rarely initially recognized as Jeeps by the average American.

Maybe if you weren't crawling over all those rocks in the SW...😉

What's "the good stuff"? Moog?

Spicer units. Going back with AC Delco Professionals, we will see. I replaced them after I returned from ouray invation 2022.

In the grand scheme of things they are seeing a good life, crawling is moderate, no locker, and moderate tire size. Just sad knowing that I replaced the originals out of this front axle that I believe is a 79…..

Did you use dana spicer parts ? All my u joints and the two ball joints i did were dana spicer.. made in the usa..

But if they reslly only lasted that long..then that sucks.

My 4.0 ZJ had to have drivers balls joint at 360k miles.. So i dunno lol

That’s what the box said lol. It’s just one….. replacement parts are still our nemesis.

Supposedly the Spicer parts are best. No personal experience - look for old posts. Another thing that's easy to find if you have the OEM part numbers.

We've had good luck with the MOOG stuff we put on the ZJ. A little pricier but they're supposed to last forever. Idk if they will, but they're supposed to.

Actually a 4.0 has more power than a 360 lol. Nearly 200hp. The 360 is what 145 ? My 5.9 ZJ is 4300 lbs and puts out 2x the power. But i hear ya

Did you happen to get thrm on amazon ?? I suspect lots of stuff there is chinese parts in a dana box. I wont order the 707611x or whatever ball joints and the u joints on amazon because of it.

Now the leaf springs i imagine dont help.. lol especially with my add a leaf lift for 2 inchs.. and my already stiff new springs i got fir added weight capacity.. the Jeep shakes like crazy on bumps. Oil shocks did help though.

But i wont lie i do miss the sagging leaf springs. It road soooooooo nice lol

Yeah, hp the 4.0 beats the 360, but in torque they're pretty equal. The 360 should have more. And torque is the bigger concern with components like that.

No I think we got them from Summit. MOOG is a name brand, high quality stuff. If it isn't made in the USA, it's still got good quality control and stuff.

The leaf springs shouldn't really have an effect on how much that stuff wears. Stiffer spring rates MAY cause things to wear out a little more quickly, just because it takes more force to move the axle, thus the joints absorb more force before the springs move. But the difference is/should be relatively minimal.

I think yet again it's just about new parts sucking and not being built to the same standards as the originals. Also you're still replacing stuff for the first time on the GW--after it sat. Mechanical stuff doesn't like to just sit. Using it too much isn't good for it either, but things go bad when it just sits. And you don't know how it was treated before you got it, or even nec. why it was parked.

Locking hubs will also help with cutting down on wear on u joints...well 5 of them anyway lol. And keep them greased up if they have grease zirks, every time you do an oil change.

If the '71 has taught me anything, it's that if you give them what they need, they're more likely to be reliable and protect you if/when they need to. Your Jeep wants to keep going :)

I daily drive it despit the gas. The one that sits more is ny 5.9 zj. And thats fine by me. Its deff wayyyyy more powerfull and faster. And better mileage. Slightly.. but i wanna keep off that whiney transmission. It works fine still but for how long ?

Reliability.. they have all been reliable if i make sure they parts are replaced and i keep ul on fluid changes etc.

I think ive put just about over 6,000-7000$ in parts on my 90 in the last 6 years...
