rack and pinion for our cars

[TheOldMan]

Great, lets see what can be done.

UPDATE: put in the rack and pinion kit Edelmann 8786 Rack Pinion Seal Kit and have to bow to RubyRed.
This kits seals looked good but DID NOT WORK. The seals leaked. Do not purchase or use this kit.

Well like I said, I will try it and give my review.

I will try another one.

D#$%!. Sorry to hear it. Hopefully MickeyTee can gain some useful info from his rebuilder in Tx. We REALLY are in deep sh!t if there's no way to solve our own rebuild problems. Add that to the lack of quality Power Steering Pumps and we'll quickly end up without a way to AFFORDABLY maintain the steering systems in our cars. Not a happy prospect.

Checking the ohms i do no believe confirms its working. Also check to see if its grounded to the housing. I saw a toyota unit video where neg volts was applied plus positve , i think 5 max in that case the rack was in a jig with springs pushing on the tie rod towards the rack.the torque to turn the wheel was measured. With no volts, then neg volts then positive volts.they had a pump set up runnng fluid thru it. I did see some manufactures offer the unit as a replacement. Ive read that the magnets are ceramic . they break easily. Old days you took a hammer to a starter and you could free it up. Today if you bump a starter housing you are very likely to crack a magnet , then its junk. So these magnets are fragile . Ive got a junk yard sending me a bad rack so it might be worth looking at and cutting up but there are no parts. A company in texas is supposed to call me. They say they rebuild the c6 which is close to ours.we will see what they actually do. 450 for a rack.
i was told that a leak is a result of other failure not the cause.

Great! See if you can find out any technical info that we can use to rebuild our own. Not thrilled about having to go down that road but I don't see any practical alternatives. I'd hate to have to join "TheOldMan" doing trial and error rebuilds on my own. The rebuild kits for the MagnaSteering units aren't too expensive but it adds up. It's also a lot of effort to keep removing and re-installing the steering racks. I'm too old for this crap.

Thanks again Mickey

iVe got information from texas . they do not repair the magna steer. They can rebuild the rack with seals and boots and i believe new tir rods. But our ars have at least three racks and they are not interchangeable. They referred me to a guy in michigan. He does rebuid part of the magnates steer. He wants me to send him some photos of the rack. He does corvette both regular and magna. He said some of the parts afe not interchangeable. But we are working on it. He said he has good success with sealing the leak if you dont tug on the wires. Neither will pull the epoxed unit out from what i understand. He sending me information to help us figure out exactly what we need if its more than a leak.

Hey Mickeytee or RubyRod, where on the rack and pinion is the part number stamped? Here is a list of numbers I have for each year.
Are they correct?
year--------- superceeds ->----------- last listed
2004-06 ...... 88964543 , 888952522 ... 19330445
2007-08 ...... 19168107 , ............................ 19330426

Im not sure if the numbers are on the rack from the factory. Gm can change a number due to a redesign or they will sometimes change if they change manufacture. If anyone looks at oemcats its a good source for part numbers and what they superceed to. Also they tell the size and weight of the factory parts box that helps in identifying some items.

I haven't examined the rack when it was out of the car. I don't know if the part # will be cast into the part (or maybe engraved) or if it may be marked using a "laser label". If a label is used they likely fall off over time from exposure to the elements and thermal cycling.

If mine has to be replaced again I'll see if I can examine the rack to find a part number. I think it's a better than 50% chance that my rack has to be replaced again.
