I'm learning? Maybe I just think I'm learning. U-joint issues.

I bought my first new/old 2006 last Summer and shortly after joined TDR. For the past 6-7 months I have enjoyed looking over the fence and snooping on the different forums; discovering how much I never knew; and, learning a tremendous amount of info that no doubt will save me time and money somewhere down the road. Thanks to each and all of you for this valuable resource.



The other day the rolling click in my drive-train forced me to admit that I better get some u-joints on the way. The factory sets are finally playing out at 199,968. As I searched the web, rolled around on the ground under my truck measuring and identifying components, and of course looking at the various posts on TDR, I became aware that our much beloved trucks can have either a Spicer or AAM drive- shaft. The universals are not interchangeable according to several suppliers. Spicer manufactures a Series 1485 (part #5-3206X) that fits the narrower AAM driveshaft yoke. It is only . 010" different in width from the Spicer driveshaft yoke. Is this tight fit enough to cause premature failure? At least two suppliers think so (Denny's Driveshaft and Northern Drivetrain), and evidently Spicer thinks so for them to manufacture this particular universal to fit the AAM driveshaft.



The new universals are due in tomorrow and after I get them in I will report back.

Well, the clickity-click is gone, no vibration, everything fit like an old boot. Measure and verify whether the driveshaft is made by Spicer or AAM. Now to move on to the next project, changing out the transmission fluid with MobilTrans SHC DC.

Welcome to the boards, by the way.

Thanks Trent, and in an effort to expand my continuing education, I plan to be in Columbus in June. Besides going on the plant tour I look forward to meeting some of you all that post here on a regular basis. Ed
