Grant Steering Wheel Horn Repair


TR6 Home















I've had a 14" leather wrapped Grant Steering Wheel on my car for about 7 or 8 years now without a problem. The other day (10/2007) I was about to turn left at a stop sign when I heard someone blaring their horn at me. The car that had just turned into the street across from me stopped and looked back at me. I looked in my mirror and there was no one behind me.................but a horn was going non-stop. As I kept looking around I slowly realized it was me honking, but when I pulled out and went straight, it stopped. I have to admit that the new horns I put in the car in the Spring are much more effective and authoritative then the original Luca horns. So I continued my drive thinking, no hoping, that it was a fluke. But the next stop sign, in the middle of the busy Choate Prep School campus, I went to turn right and off went the horn scaring a bunch of co-eds and faculty. Ooops.......... time to pull over and pull that fuse!

When I got home I pulled the steering wheel and adapter hub from the car and found a spring and a pile of copper dust in the column hub. There was also a copper rod that was slightly bent and obviously worn on the tip. It didn't take me long to figure out that the spring is supposed to be held in place over the rod by a "cap" of some sort so that tension is maintained on the rod for it to make contact with the copper ring in the column hub. about a run-on sentence!

I called Grant's Customer Service number and was put in touch with one of their design engineers. He knew immediately what happened and asked what I had used to lube the end of the rod..............lube? I told him I was looking at the installation instructions and there was no mention of using lube..............after a pregnant pause on his end he said, "anytime you have metal to metal contact, you need to use some sort of lube. Oh. As it turned out he hadn't designed the part so he had to refer it to their Italy plant and, in his words, "they aren't too good about returning emails.  So, in the meantime, I've come up with my own temporary fix as shown below.

First up is to drill a small hole in the end of the rod
Then a thin cotter pin to hold the spring in place
Clip the cotter pin and you're good to go

When I put it all back together I used some white Lithium grease on the copper ring on the column hub and, hopefully, we'll be good for a few more years.
