On my 1985 IROC, there is a intermediate shaft from the column to the steering Box. On the shaft is a universal joint( in good working order), but the rubber boot is broken. I would like to replace the boot(While the motor's out), but if needed will replace the shaft. GM does not even show it in their system, so : Any one know where to go from here?

 

are you talking about the part right at the steering box from the shaft? If so, that is a rag joint. Any auto zone will sell it, around $10.

 

Not the rag joint, but on the intermediate shaft, there is a universal joint, inside a rubber boot. I'll try a picture.

 

Here's what I found for 85: Shaft, inter (W/WS6, WS7) 7839607 and Shaft, inter (Exc WS6, WS7) 7839606

HOWEVER, note below (I'd like to give credit to the original poster, but I can't locate the info's origin). This is the box, not the shaft, but I found it interesting nontheless.

• “WS” – 1982-1992 Camaro – 12.7:1 ratio (just like your Z/28, this may be the box that you Z originally had.

• “XH” – 1985-1992 Camaro – 12.7:1 ratio (this box was also installed on Z/28’s and other high performance Camaros; it has slightly more steering effort required than the WS box.) NOTE – I believe this box was used on cars originally equipped with 16” wheels

• “WN” – 1982-1985 Camaro – 14.1 ratio

• “WP” – 1982-1985 Camaro – 13:1-15:1 variable ratio (used in Berlinettas, least steering effort required of all third gen. Camaro steering boxes)

• “JL” – 1986-1992 Camaro – 14.1 ratio (base Camaro steering box)

Id like to know if GM even carries these anymore. I would like ot replace the worn out tired one in my car

 

I belive the shaft is discontinued, But some one on ebay is selling new ones. Im not sure if there original GM or aftermarket but they are going for about $100.
