Default Power steering pump - rebuild or replace?

with 135k on my truck the suction hose and o-ring seem to be leaking on my power steering pump. The rebuild kit is about 20 bucks and a new pump is around 60. The rebuild kit is only seals, no vanes, sometimes has the bearing but i wont likely replace that.

is it better just to replace the pump at this many miles? my concern is that if i reseal the pump, it will not produce as much pressure as a new pump. it also just occurred to me that i dont know if reman pumps replace the vanes.

anyways, if someone knows about the vanes or has a suggestion from experience id like to hear it.

i dont have the patience for taking one apart and rebuilding the thing. i just replace those things. it would be different if it cost 150 bucks for a replacement. i look at it this way.....if i spend 20 bucks on the rebuild kit and something tore up (broken vane or who knows) than i have to buy the reman unit anyway. the warranty on the replacement dying is on someone else.

135k doesn't seem like too many miles on these trucks.

Has your steering pump had a hard life? If not and it's just leaking ...and you know how to rebuild stuff ...and you have the time ... DO IT!

Then, just sit back and think about all the things you are going to do with that $40 you saved.

Years ago I worked for a power steering remanufacturer in Phoenix, (pumps, gears and rack & pinions). We use to reman around 2000 units a day and shipped to AutoZone, Checker and a variety of other retailers. At that time the vanes were replaced and the ring they rode on was resurfaced. What happens today I have no idea, it's a cut throat industry.

We had a Tech Support line and the most common complaint was a noisy pump which was caused by air in the system. The best reman kits came from Freudenberg NOK, their seals/parts were used to build new OEM units.

I rebuilt mine years ago, when it still had the Z24i in it. It was pretty simple, and the leak was one of the o rings. The pump had about 70,000 on it when it started leaking. The rebuild was still going strong at 217,000 when I did the engine swap...

Mine is still going strong 3yrs after rebuild. I think the kit was 15 bucks on ebay. It wasn't hard and I figured I would take more care than anyone else would. No regrets on the rebuild here.

its amazing really. it looks just like an old dirty power steering pump that was recently fucked with.

although, i did spill PS fluid on everything. so i took the truck to the car wash and used the "presoak" on the engine bay and rinsed it off really well. the underside of the hood was black and i never noticed. its kinda silver-ish now.
