I purchased a Woody replacement shaft for my TJ a few years back after installing a SYE. Since then I am now on my second rear joint. This last change I was almost unable to remove the shaft from the rear pinion yoke. The shaft would not collapse without the use of a large pry bar. After removing the rear joint and the rubber boot on the shafts slip spline, I had to use the hydraulic shop press to separate the shaft. Even after cleaning and lubricating both halves really well I could not reassemble the two without the aid of the press.
I eventually stripped off the blue Teflon(?) coating from the splines. Which now allows the shaft to expand and compress.
Just wondering if anyone else has had a similar experience?
