Default rack and pinion question

Can someone here provide me a list with parts and (if available) partnumbers to do a DIY rack and pinion conversion ? Thx

Karsten (MyBad79) loaded some great info in the downloads section - under chassis & suspension. (Includes some part numbers as I recall.)

I've got some diagrams to build mounts - I can search out that were measured diagrams from some Speed Parts mounts.

Cheers - Jim

I did that conversion on mine. Not to bad at all. I made one mistake though and I made the center bracket about two inches too short. I bought more stee lto make it, just havent had a chance to do it yet.

I THINK I may have some diagrams still on file from my rack conversion, I may have uploaded them here, but I did my rack conversion winter 01-02 so it's been a while, the rack came from a '89 Grand Am, junkyard find of a new/fresh rack for 35 bux.....a welder buddy made the mounts, the one on the pass/right side is easy, the one on the driver/left side too two attempts, the input from column to rack was pieced up from junkyard parts from Lumina series mini vans....as I recall.....I took the universals apart, and pieced them together as needed to make up the linkage, it took only two universal joints and not 3 as with the kits.....so no need to support the intermediate joint....the trick is, I used the OEM tie rod ends, so no change on the suspension, just got a machine shop with the correct taper reamer to make the adaptor plate for the rack CTO.....my tie rods are 19 and 21" long, so not equal length, I should maybe have adjusted that center mount to make them equal, but I see nothing to gain for the effort over the years....

IF the sketches can't be found here, PM me and I will scratch around to see if they can be sent.....

Yup, did it for not much $$$$ ... All new parts, rebuilt rack .... It was fine but it has developed some play, haven't had time to dig into this but I'm convinced the brackets that I built are rock solid, I'm suspecting the rack itself ....
Another thing: the manual rack from the Cavalier or GrandAm is 3.75 turns lock to lock - not all that great but very easy to turn.... I have a power rack with 2.5 turns lock to lock and will try that without the PS pump to see if that ferls better .... Not happening anytime soon but when time comes I will definitely start a new thread with more pics ....

Where did you get the rack from ?

All of the other cars I've ever driven here in Europe are rack and pinion. Can't remember I ever had one that developed play, other than at the joints.

Unless you are lucky and find a Pick-and-Pull that has one- eBay is you option. Here are a handful - all pretty much less than $100.

Some include free shipping world-wide - with a few exclusions. At this date - the best you'll find will be a remanufactured item.

Good luck with the project!
