[vwynn]

Outside of failure, Around what mileage do most LX owners start replacing or considering replacing their globes?

5-7 years.

Behind general maintenance, the purpose of the exercise was to just get everything leveled out. This is one of those situations where the phase "better is the enemy of good' comes into play. I'm going to get back on this tomorrow but need to get additional fluid.

put a floor jack under your breaker bar and put a little bit of upward pressure while you try to loosen the globe.

Or use the handle of the floorjack as an extension of the breaker bar…

The hexes have been known to round or snap off the globe. The floor jack trick helps prevent that failure mode… so you are more likely to get away with said breaker bar extension

'11 LX570 w/ 170K Miles.

I 'attempted' to change the globes today. Did my research and tried to follow the directions but things went south when I could not get ANY of the globes off. I had breaker bar but zero luck. Assuming they have been on there since the beginning of time. Rather than leaving it, I decided to refill it and get it back on the road. Fluid back in, started the bleed process, DF, PF, DR, PR. From What I could tell (note, first time bleeder here), I had fluid coming out on all corners and no air. Cycled through Low, High, Low but my ride height is all over place. As a result, the system is having trouble locking in on L, N, H.

Is this a sign that I need to re-bleed the system or that I may have overfilled or underfilled the reservoir? I say the last part because I can't see the min / max line, even with a flashlight, so I had to eyeball it based on fluid I took out.

Appreciate your assistance on diagnosing this. Thank you.

Grind the chamfer off a 13/16" socket and gently tap it on to the globes. My globes were quite rusty and a 24" breaker bar took them off relatively easily.

For the fluid level, go in under the truck from the rear, next to the spare tire. You will be able to see the rear of the fluid reservoir. Stick a flashlight up there, which will backlight the reservoir and allow you to see the fluid level from the access door in the wheel well.
