Full Rebuild of my R34 Skyline Power Steering Rack

[@pkd4697]

Wow. . .I am going through it with the rack and pinion on my Gen 3 4 Runner! I just went the way of the Replacement unit!! Looks like I dodged the wild rebuild route!! You are brave to take this bad boy on!! Glad you are back!!

[@TheBuildRoom]

Thanks man its good to be back at it - hope the 4 Runner is back up and steering again! 👍

Great vid. Gotta do this to my p10 so it was good to get a look at a similar rack

[@satz5964]

Great work and nice videos. Thanks a lot for the series. I had an R34 25GT myself in red between 2010 and 2014, right before I got myself a black 25GTT. I did some work on them myself as well, belts, plugs, injectors etc. My steering rack is currently leaking at a rate of the cylinder going from high to low measure in about 30k km, so I will not be rebuilding it anytime soon, but when I will your video is going to come in handy for sure. Thanks a lot!

[@TheBuildRoom]

Thanks, glad you liked the vid. If you're only going high to low over 30,000kms you might find just some fluid with sealant additives might keep you running for a while longer.

I didn't miss a minute of this episode although I don't even have an R34! 😁Great job as always, and kudos on persevering through the hurdles. Can't wait for the Celica content! 👍

[@TheBuildRoom]

LOL thanks Bermil - I'm keen to get back to the first gen stuff too - not long now!

[@daos3300]

great walkthrough. i'd have used a low viscosity grease for closed gears (EP/NGLI 0 or 0,5). EP/NGLI 2 squeezes out of the gears and they can end up running dry, also marginally increases friction in the system. another tip is to put the seatbelt through the steering wheel so it doesn't move off centre.

[@TheBuildRoom]

Interesting - haven't had any issues with it so far and have done a fair amount of kms but will keep the grease info in mind for the next one. Thanks

[@xxdarkcarl]

Do you have a parts list for the steering rack. Specifically the pinion bearing and what not

[@5iibee]

Helpful video, just done my rack. You don’t need a tool to get the seal out though, you can knock it out from the pinion side with a socket and extension 🤙🏻

[@TheBuildRoom]

Wasn't enough left on my seal to catch the edge with a socket, but good info for people that might not have too much wear and can get it out an easier way 👍👍

[@5iibee]

@@TheBuildRoom I wonder if I have a didn’t rack version to you because mine had a thick metal washer behind the inner seal which is what helped me knock the seal out from the other side 🤷🏻‍♂️

[@ralph5476]

Many thanks for this informative video. Would a suitable sized socket + extension in the rear end push out the recalcitrant seal?

[@TheBuildRoom]

Glad you liked it. Doubtful any socket would work to push out that seal. The seal seats down onto a metal lip and the internal diameter of that lip is only a hair wider than the ID of the seal, so it wouldn't have enough meat to push on. The seal removal tools come from the other side and expand into the seal to pull it out.

[@ralph5476]

@@TheBuildRoom It did seem a tad too obvious, so I sorta figured it had to be something like that. Thank you.

I have been looking for the dental floss!

[@TheBuildRoom]

🤣

[@sjgoff]

Great video! I should have rebuilt the rack in my S13 instead of replacing it...

[@TheBuildRoom]

Lol to be honest I'm not eager to do another one of these, but at least I can if i run into one again.

[@Dnasty1]

Hey great video. I don't really have the space, equipment or knoweldge on rebuilding a rack. But i bought one off ebay and while it does not leak it makes a bunch of noises and pops, and it makes that thumping noise when you turn the steeringwheel left/right very fast. I took it off my car and put the original one back on as they both seemed similarly worn The ebay seller let me keep the rack for free when i tried to return it. Since then though my rack has developed some play on the rod part and a clicking noise and starting to cause weird suspension problems. I was thinking of taking my ebay one to a rack rebuilding shop. I was wondering if the issues I mentioned would fix this rack since there is no leaking issues. Or will changing all these parts make it function like a new rack?

[@TheBuildRoom]

Are you sure the play and noises are coming from the rack and not the tie rod ends? If it's just worn out rod ends you can replace pretty easy with the rack in place. Otherwise you'd need someone to inspect your rack, it could be a bust bearing or something. Seals and bearings are fixable, damaged gears not so much.

[@MikeyGTR]

Which sealant did you use for the adjuster?? Great video by the way 👌

[@daos3300]

at a guess, the one that's lying on the bench

[@MikeyGTR]

@@daos3300 Good spot i didn't watch the whole vid lol

[@TheBuildRoom]

Yep the one on the bench - thanks for the feedback, hope you got yours sorted 👍

[@MikeyGTR]

Yep all done, thanks to your great informative video :)@@TheBuildRoom

[@deiangonzales8406]

So where did you source the upper pinion gear seal? part #? need to replace exact same seal on 2015 Q50 V37

[@TheBuildRoom]

A local power steering company sourced for me, wasn't expensive and they had it listed.

[@repairstudios6748]

When installing pinion gear, do I have to adjust the fluid holes or not? or it can be installed directly without considering the fluid path

[@TheBuildRoom]

I'm not sure what you mean bu adjusting the fluid holes?

[@sushisstreetgarage]

Awesome video. Very informative. Kudos for you attempting this. Looks stressful 😅

[@TheBuildRoom]

Yeah wasn't a fun job but am pretty confident i could do another one a lot more easily now. Glad you liked it 👍

[@howardrathbone2120]

How about using an electrical conduit, which is plastic, and push the seal out from the other side? Would that work? How long did the rebuild take approximately I have a leaking 350z steering rack I’m thinking of rebuilding?

[@TheBuildRoom]

Nah i don't think the lip of the seal has enough strength to transfer enough force to shift the seal - its a tight one. I'd recommend just hiring a tool.

[@howardrathbone2120]

@@TheBuildRoom and approximately how long do you think would be a reasonable timeframe to allow

[@howardrathbone2120]

Hi, did the pinion seals come in the pspa kit?

[@TheBuildRoom]

No I got them separately from a local power steering specialist

[@howardrathbone2120]

@@TheBuildRoom I’m in Albany and have a 350z steering ack that needs to be rebuilt, can you tell me who it was you dealt with so I can order the parts? Great video by the way, cheers Howard

[@TheBuildRoom]

@@howardrathbone2120 yeah no worries man, it was Power Steering Specialists in Malaga. They ordered it in but it only took a couple of days, and had it listed so no guesswork.

[@drnc8770]

Where is the solenoid on your ps rack? I have an r34 gtt and my rack has a solenoid on it.. What is the difference between the 2 racks?

[@drnc8770]

Nobody know?

[@Glock18Kid]

Yeah mate, that is actually a difference between a non turbo and turbo r34 steering rack. The solenoid on the gtt is for variable steering assistance, so at low speeds it will assist the most, and at higher speeds it will be very little assistance. Apart from the solenoid, the racks are pretty much the same @@drnc8770

[@jcgarcia4575]

Stupid ways to fix rack and pinion, time consuming

[@TheBuildRoom]

What would you have done?

[@comaradelee]

will the rebuilt steering rack make the steering light again after the rebuilt? mine is stiff

[@TheBuildRoom]

@@comaradelee mine lightened up because it was leaking previously and now has full pressure, but it really depends on what is causing yours to be stiff (could be other suspension components, wheels etc)

[@comaradelee]

@@TheBuildRoom thank you for this

[@TheBuildRoom]

@@comaradelee no problem, also might be your power steering pump, if it can't build up enough pressure it's would definitely be heavy
