Power steering service and life

Long story short, power steering pump took a dump last night. 107,000 miles and its only been drained and replaced once. Wondering how often you guys service (if at all) or how many miles you saw before needing to repair/replace. Limped it 45 miles home last night and added 48oz of fluid on the drive. Woke up to the rest of it on the driveway, can't find anything obvious but assuming the drive home with low fluid cooked the pump.

 

I would expect the steering rack to start leaking and cause fluid loss long before the actual power steering pump itself.

 

I'm at 115k miles on my 2014 rack and ran 37" tires for first two years and then 40" tires from 2017 until now and have zero issues. I do a drain/fill of the steering fluid every 5k. I also swapped out my OEM rubber bushings for polyurethane around 50k and am about to throw in a fresh set of poly soon.

 

Shop just confirmed this. Was not the pump. I assumed it was only because the truck still drove fine for the most part. Was thinking a bad rack would cause wandering, loose steering and at least have audible binding or popping noises. I heard nothing besides the groaning.

 

Typically they will just leak and you'll see wet spots around the boots and the rack itself. Do be sure that whatever shop you use puts on a new Toyota rack, not a rebuilt one.

 

OEM rack is what's going in (unfortunately $$$). They stated it's a 13hr job on the books but they're confident it can be done in 6. So looking at 1700~. Little more than a pump which I was hoping for (and can do in the driveway) but it looks like the rack assembly is a decent job to pull it. 108,000 miles and only the 2nd issue I've ever had (failed sending unit and fuel pump at 64k~) so not at all upset. Just bad timing (as always)
