2015 LR4 126,000 miles What Preventive Maintenance to do next?

The poly bushings also change the loads on the control arms, where impacts that used to be absorbed by the rubber now aren't. I remember seeing a picture of a failed control arm in a post here, where the metal around the bushing at the front of the LCAs gave out (@djkaosone was it you?) For how much we drive our LR4, 70k miles will take 10+ years, so an OK replacement interval for me.

Oh yeah, that was me. I had about 1 year on the Lucky8 polys before it left me stranded on the simplest trail. I've done some pretty tough trails before and lead me to this failure. I really think the polys are too stiff and stresses the load to other parts of the LCA.

Tires, tires, tires.

Tire air pressure: https://tiresize.com/pressure-calculator/ Additionally, read the section on differences between the different types of tires.
Wheel fitment: https://www.wheel-size.com/calc/ pay attention to scrub angles, clearances and aspect ratios.
LTs + lower profile = train car wheels to me.

Personally, I would have gone down to 18"... if they would fit.

That control arm looked dangerous. If that came apart on the freeway it would be a rough experience even with a good landing.

I just received the OEM Lower Control Arms. I also learned the rear busing has fluid in it where the aftermarket does not.

I will replace them and see if the ride harshness changes.
