Gates 348558 Power Steering Repair Kit

I bought this kit to take care of a leak in the power steering pump in my Acura MDX 2008. After disassembling the pump, I checked every gasket/seal against the original seals in the pump. Everyone was an exact fit. I replaced everyone of them. If you have not done this job before, be aware that the main shaft oil seal replacement requires the removal of the bearing. That is the most difficult part for this job because you can either damage the housing or do damage the spring circlip while removing the bearing. After that is done, reassembly of the pump is easy. Another care to be aware of is the metal flaps that come out when opening the pump. These flaps or tabs have only one way to be in the pump slots. One side of the tab is square while the other end is curve. The curve side goes out and it is curve to follow the smooth surface of the pump casing. Be aware to install these tabs/flaps in the correct position. We shall see if the life of these seals is as good as the original seals.

missing a single small o ring, oem has 4 and this kit only has 3

It is fairly typical that the power steering pumps on Honda/Acura vehicles tend to leak after 10 years or so. This kit repairs most of those leaks. It is relatively simple to install.Total time is about 2 hours from removal, rebuild, and re-install. You will also need Dorman 926-157 Multi Purpose O-Ring for Select Acura/Honda Models. This has the o-ring for the power steering hose. You'd be crazy to not replace that o-ring when doing everything else.While you're at it, drain the power steering pump reservoir and replace with vehicle specific fluid.There are plenty of videos out there showing you how to do this. Watch them and you should be fine.I've done this on four different vehicles and they're all leak free now.

I'm a big fan of Gates and have used their products for years. I didn't price individual Honda o-rings so I can't speak to the value of the Gates kit versus buying OEM replacements. Most choices for which seal goes where were obvious (comparing o-ring size, thickness, and diameter), but I couldn't find a good fit for the high-pressure line. I had a hard time getting the high-pressure line seated without the o-ring getting snagged. I finally got it to stay and tighten down appropriately. My guesses for replacements have worked so far, the cavitation has stopped and there are no obvious leaks.The instructions, while available in multiple languages, are basically useless. Get on YouTube and watch videos of other people doing the rebuilds. Don't just watch one, because there are different approaches and some work better than others.If you're going to flush the system, I would recommend not using a turkey baster. Spend $10 and get a siphon pump (I used the red pump-handle kind). It can suck all of the old fluid out of the reservoir, and in my case (again, remote reservoir) I disconnected the return line to the reservoir from the rack and ran into the siphon pump to suck out the old power steering fluid.Also, don't over-tighten the pulley when you reassemble. This added a decent amount of time onto the job because I had to take the pump back off to get it to be able to turn again.

The shaft seal and gaskets appear to be holding up for now. The main housing gasket seems to be on the thin side (not much compression) but it isn't leaking so it may be fine. It's only been two months since I installed them. We'll have to wait and see if they hold up more than a year.

Perfect as shown and works well

I finally was able to have time and rebuild the pump by replacing all the gaskets. I did track down the shaft bearing, I do recommend replacing it, of course if your vehicle has over 360,000 miles like are 05 Honda Pilot, but that’s up to you. I didn’t give 5 stars due to the gasket set DOES NOT come with the high pressure line rubbero-ring. I had to end up buying it separate. I ended up getting it from local honda dealer. All and all, I only spent, roughly, $18 on bearing, $ 2.50 extra o-ring, and $30 on this rebuild kit and the pump works like brand new.

Great product and at a awesome price what else can you ask for. Great communication and delivery was spot in

this kit does not include the o ring for the high pressure hose. fits perfectly and works great

I liked it it was perfect set
