Steering clunk..possible fix

So, just like a lot of you I have the steering clunk that developed after 40k miles. I had it on my LLY years ago and I replaced the ISS and it fixed it a short time. Then the band clamp fixed it all together.

So, I start this on my LML now...I replaced the ISS on my LML last week. The clunk is still there. I was determined to figure this out. This may or may not be your issue or your fix, but it worked for mine.

While replacing the ISS I noticed the steering wheel portion that the ISS slips into was loose, but has no play when the ISS is attached.

So I replaced the ISS, tightened it down etc. This morning I got under there and started wiggling the ISS and I immediately hear the rattle/clunk. It's the joint between the ISS and the steering wheel shaft itself. It's the vertical play on the joint itself.

You can crank that bolt/nut down as much as possible and you will have no horizontal play, but vertical play still exists.

I loosened the ISS and removed it from the steering shaft. I put electrical tape around the ISS joint male portion and then put it back inside the female portion. It was harder to slip in there, but finally did. the tape stripped back a bit and acted as a buffer. I tightened it back down again and what do you know..... NO CLUNK!!

This may or may NOT be your issue, but it sure as hell fixed it for me. I know it's not a fix it all thing, but I now KNOW where the clunk is coming from.

Save yourself money on a new ISS and just crank down the stock one and put some tape or something on the ISS male side and try that first.

Hope this helps.

you'll need a 13mm box wrench and a 15mm ratchet.

first one is the NEW ISS with the tape installed.
