Hi guys:
Waylan, oh you mean that ! Now I get it... . I simply went to Dodge parts, asked for the intermediate shaft, they gave me a superceeded (twice over) part # for my year, and my impression was that it looked re-designed and stronger than my original stocker (which had been tossed when I installed the Borgeson, so I can't do a direct comparison, sorry).
But, my Borgeson was stuck fast, and besides I suspected it was a large contributor to the 'clunk' manifesting. Of course guys with stock OEM shafts also have the clunk, but I noted on my extensive researching of thousands of posts & threads that quite a number reported having the 'clunk' get worse, after using the Borgeson.
That, coupled with the fact the new, apparently improved OEM shaft was available immediately at Dodge parts for about 1/2 cost of the Borgeson part, is why I chose to do so.
I believe the parts person looked up the #, and it was for all 2nd gens across the years, so the superseded part is a 'new' updated one for most / all Rams. $ 153. 00 - not too bad, I thought.
Hope that helps.
Willys,
Your description fits what I felt to a 'T'. Felt in steering wheel and pedals area. Makes sense, it's originating down low in the footwell / firewall area, hence vibrations felt there in your feet, and the telegraphing 'up the column' to the wheel.
[First the clunk I felt was at highway speeds over broken pavement joints, then later, sensitivity seemt to increase, to when stopping or starting and on every rough surface or dirt road it would 'clunk or rattle' repeatedly. Stopped driving for a month, thought the wheel was going to come off in my hands. ]
Grabbing the spring/lower column end and trying to move the mass of your truck using that as a 'handle' should reveal any play.
I wouldn't say mine had so much that I said "wow - that has to be it. " I did say, 'hum, I think that could be it' - So I proceeded on faith to pull the column - but a few others were certain that was it - SMorneau had located it with certainty, and employed an effective home brew fix, but most either suspected it and ignored it, or had the dealer replace the column multiple times @ $ 500 - 800 each, and with the same weakness - not a sane solution !
Durability - what Waylan shared about steel being worn by grit, not the Delrin is what I suspect is the case, from his ATV experience. It also makes sense that our columns have quite a bit more isolation from grit as they're underhood, high on the firewall.
No hey, no offense taken that's a good suggestion. The lube hole, and maybe a sealing boot of some sort, if required.
It will be good this winter, for us who drive in nasty conditions, to observe if crud makes it that high when splasing through mud puddles, etc. I don't see any evidence on my firewall that it does.
We make the bushing tight within a couple thousandths, so there is tiny gap where lube can be sprayed between the inner shaft & bushing. Plus the Delrin is self-lubricating.
The bearing surface area is now about 4x what the stock one was, and uniform to boot. Hence the tighter fit & improved road feel - the road forces aren't trying to balance on a tiny, thin undersized bearing with a forcing cone & spring trying - and failing in the long run - to keep everything aligned.
I appreciate your questions and suggestions, and hopefully this is of help to you in a practical sense.
