Are the aluminum steering knuckles really a problem?

[Metalhead]

Planning out my lift and tires. My rig will be for overlanding trips and not rock crawling but could see some rough trails. I have read some things about the aluminum steering knuckles and want to know do I really need to replace them? I will be doing the mopar 2 inch lift and running 255/85R17 micky thompson tires on the stock wheels.

I have a 2018 early production JLUR and I have run a Mopar lift since probably 700 miles or so. I have 102,000 on it now with 2 trips to Moab and countless other off-road excursions. I´ve run 35¨ tires also for a few more miles than the lift. There has been no issue with those knuckles. I don´t do any pre-running, like the Mojave is set up to do. That type of wheeling is exactly why they put the stronger steel knuckles on there. I do lots of rock crawling and overlanding-style trail running, too.

The Mojave was meant to be Jeep´s Raptor. It is made so that you can hit whoops and get a little bit of air and come down really hard on that front end. That´s stuff I wouldn´t even do if I had a Mojave, which is built for it.

But I have not babied mine, either.

One more thing...last time I was in Moab...maybe 2 years ago, a Jeep rental company owner told me the JL´s were holding up far better than the JK´s ever did. He never mentioned an issue with those knuckles. You can imagine what people put a rental through. And those rentals were all on heavy 37¨ tires.

So I would not worry about it. Then again, I do drive through the pot holes of Indianapolis, so maybe I should. LOL!

I agree with everything you said. Since I do try to do Mojave things with my “used to be a rubicon”, I replaced my knuckles with the same ones a Mojave gets. But mine sees harder hits.
