Wobbly tilt steering column repair w/Marc H pin

As we all know, Marc Haibeck has solutions for our cars and lives and breathes for the survival of our ZR-1s and LT5s. Although this is a standard Corvette and other GM problem with people trying to use their steering wheel to get in/out of their cars, he came up with a fix for the most common problem.

Mine was experiencing the wobble from top right to bottom left if that is the right way to describe it. I was going to go the domestic misfits link route: http://domesticmisfits.net/forums/viewtopic.php?t=124 until I consulted with Hammer (John) and Marc about this issue.

Marc has the enlarged pin that he sells for $50 and even though I thought it was expensive for a pin, I feel that it is well worth it now. Due to the close tolerances these are made and the small order, he explained the price. He said I should only need one for the left side so I only bought one and figured if I was not happy, then I can do the other side.

So the repair is very easy with minimal dismantling (sorry, no pictures).

1. Remove the hush panel or what ever they call it under where your knees are if sitting.

2. Remove the aluminum looking knee bolster thing with 4 bolts (10mm).

3. Remove the tilt column knob by loosening with a small wrench (did not note the size).

4. Loosen the dash gauge cluster bezel trim (4 screws/phillips head) to manuever it out of the way and ensure nothing hangs on it. Not sure if you really need to do this, but I found it hanging when I lowered the column and did not want to take a chance.

5. Remove the two 15mm bolts and bracket that hold the column up and lower slowly.

6. Remove the two plastic covers that cover the area shown here to expose the tilt column pin that will be replaced

7. Use a screw to remove the pin by threading in and pulling if really loose or like I did and use the Lisle tilt wheel pivot pin puller (Ebay $8) like I did. The threaded hole in the top is where the tilt column rod was and right below to the left you can see the pin that you will replace.

8. After I removed the old pin I simple put Marc's enlarged pin in and lifted the column a little to push it in by thumb as far as it could go and tapped it with the hammer. Then I used a brass punch to whack that sucker in all the way until flush.

9. Put the column back up with the bracket and two 15mm head bolts nice and tight. Then everything else in reverse order.

10. Test out the tilt and feel the different. Almost like new with very little movement and it feels solid. I'm happy and won't try to do anything else. Marc stated that even when new these cars had a little bit of movement and might be all that I am feeling because it is solid feeling.

Next project is to remove the stock airbag/bus wheel and put on the Momo Competition wheel with NRG hub and quick release/lock. No wheel in the way should make exiting an entering easier as well as not leaning on the wheel to get out. Have to just do at least 50sit ups a day to strengten my stomach muscles. :cheers: Big Thanks Marc and John.:handshak:
