Powersteering Rack/Lines Questions

I have a questions about power steering lines and rack replacement on my 2005 DC 4x4 4WD. My truck still has the original rack and lines. The rack has a seep (right boot is wet), not even a dip. At this time the lines are not leaking but the lines are really corroded and look like they could start leaking and or fail at anytime. I am attempting to prevent catastrophic failure (lose a line and all the fluid) while trying to be budget minded about part costs and OEM vs. aftermarket. I have a couple good mechanics to do the work for me but my concern is getting them the correct parts for the job that are reliable but not cost prohibitive. I've researched this topic quite a bit but I still have some questions.

I would also like to hear folks opinions that have been in this situation before. I thought about just pouring in some Lucas power steering leak stop but that won't fix my corroded lines. Also it would very difficult if not impossible to remove the existing lines from the rack without ruining the rack do to all the corrosion.

My questions for the community:
1. What kind of steering rack should I buy? Reman aftermarket, I've heard bad things about some Reman but read good things about Detroit Axle which is about $215 on ebay or rack doctor for $400. 2nd option is a reman from the Toyota dealer for around $500. 3rd is new OEM $800-$900 (way to much in my opinion) online. I'm leaning towards the cheaper reman but still have QC concerns.
2. What are the OEM part numbers for the complete power steering lines for my truck? I have been having issues trying to find the exact part number. OEM lines are crazy money ($600-$800) but I found what I suspect is the correct aftermarket part: Sunsong 3402996 on Rockauto for around $130. For whatever reasons there are like 8 different power steering lines for 1st Gen Tundras.

Thanks for all the help. I want to plan this job out and get it done ahead of any failures. Any information, tips, experiences or suggestions are greatly appreciated.

 

I do not have your problem, but can say many here have been happy with both the remans you suggested in #1.

As far as the lines, you’ll be better off using all new OEM in your case as the bends, turns, lengths, etc. will be spot on. Plug and play, basically.

Enter your VIN at toypartsdeal.com and continue your due diligence on the lines. Your entered VIN should direct you to the proper part.

 

I'd go with this new one. Has inner tie rods included. Lifetime warranty

CVJ reman has OEM remans for about $400. I've used them for axles twice and had great luck with them. Highly recommended. The steering rack isn't on their website, but if you call, they do have it.

I had a leak in mine and used the lucas stuff about 2 months ago and it appears to have stopped the leak. I don't have corrosion on mine though.

 

I used Detroit axle rack no issues

For the lines i looked on rock auto and used google and eBay to find the cheapest

 

I just replaced the rack on my 05 DC 4x4 with the Detroit axle one and will use them again when I replace the rack on my wife's Sequoia. I figured for almost half the price of rackdoc and a lifetime warranty, why not? Quality looks good and its performed perfectly so far. They include a return label and you just throw your old rack in the box and drop off to activate warranty.

The part number for the PS lines is the same one I would order.

If you are mechanically inclined replacing the rack is pretty easy, just dont forget to get the rack close to center (like me) before installing!!!

 

Ok great. Quick follow up...so this part https://www.rockauto.com/en/moreinfo.php?pk=7653116&cc=1431003&jsn=10930 matches what I got for an OEM part number from the dealer. Is there a power steering pump cooler on these trucks? That has additional lines? I want to make sure I have all the lines necessary for this job.

 

Another option for the lines is find a shop that does hydraulic lines, take your old ones off the truck, and drop them off for new ones. The place I've used in my town is significantly cheaper than even the aftermarket lines. The downside there is then your truck is down until you get the new ones.

 

Im not around my truck so cant say yes for sure but it looks like there is an additional cooling line for trucks with tow package which I am assuming your truck has.

You can also use Valvoline MaxLife synthetic ATF in the PS system as the new fluid

It’s the same stuff i use for my ATF

I flushed my reservoir and everything

About $17 a gallon jug at Walmart

 

All great info....I just looked at my truck and I'm pretty sure the diagram attached is the complete power steering line setup. That looks like a lot of little parts and a couple different hoses. I'm assuming the 'cooler' is the horseshoe type hose that is labeled as 44420. Seem like a lot of hose to replace.

 

Thats a very similar looking diagram to the 2002. If it was me, I’d probs do the PS pump at the same time, as well, and be done with it. A complete system renewal.

 

Good point about doing the pump at the same time. I hate to replace a working pump with an unknown quality reman. I've heard a lot of not so good stories with your run of the mill reman pumps. That's why I'm so deep into making the decision for rack replacement. One of my mechanic friends says he doesn't even want to install the cheapo reman parts anymore because he's seen so many failures. He swears by OEM whenever possible.

 

I’d do the OEM PS pump. That Rockauto line set is OEM but not branded by Toy. The steering racks all have good reviews from members here. I’d go with the lifetime warranty one. If it fails then send it back for new! Somewhat easy DIY or pay the mechanic the extra labor to do again but it probably not need it.

Here are some boogers I blew out of my PS system. I wonder if they were clogged/gunked up in my PS Pump impeller?
