If the know feels "mushy" when turning it back and forth the problem is with the nylon bushings. Rotate both headlight ***** to get the feel; the headlight should move immediately (though very slightly) when you rotate the **** in either direction.

You will need a long torx or ball driver to access two of the screws holding the assy in place.

Then a drift would be useful in removing the drift pin that holds the headlight to the motor shaft.

Once the motor assy. cover has been removed you will need work on sliding the large plastic gear over the worm gear but it will come. File a flat on the large nylon gear to assist in installing it.

You can purchase the bushings from MAD, Eckler's, Corvette Central or even from HomeDepot like I did. If you go to HomeDepot, ask for item number 859609.

You will need six of the nylon spacers to repair both lights. Good luck!

If it's just your bushings, the nylon spacers from HomeDepot all the parts you'll need. The rest of the repair is labor intensive, but you can do it yourself with tools you probably already have in your garage.

Since you indicated you have an '86 (no bushings used in that design) I'd suspect the gears. If you end up needing gears, you'll have to get those from MAD, Eckler's, Corvette Central or one of the other Corvette speciality catalogs.

The link I sent you details how to remove the headlight bucket, open the motor housing and replace the gears and bushings. You can run a search in the TechTips section on this forum to get detailed instructions, too.

If you go with Eckler's for parts, the ’84-’87, replacement gears are PN 26670 (small gear) and A3526 (large gear.)

Good luck and holler back at us if you need any further help. I did this repair last summer using the HomeDepot bushings and my lights have worked like new since.
