The universal joints (UJs) in my 5.0 Lite NC Fairlane are shot. I have discovered that it has an Aluminium prop shaft (well unlike the one in my NB, a magnet won't attach to it or its ends). The Ford factory manual and some aftermarket ones warn that you need endurium coated UJs so the steel on the bearing caps doesn't react with the aluminium and cause premature driveline failure (I assume corroded then cracked shaft ends).
Ford have UJs to fit at $67:00 each but my dealer can't tell me if they are coated or not but says no seperate UJ part is listed for the aluminium compared to the steel shaft. Does anyone know if these $67 UJ from Ford are coated as prescribed?
I can get good quality aftermarket uncoated UJ's SKF branded for $21 each (SKFBEA1094 OR RUJ6000 OR K5-13 XR OR VKUA K5.13XR OR UJ 38.9811 - Five different part numbers on the box).
I found have found a supplier of coated UJ's in the USA - Neapco See their catalogue at http://www.neapco.com/pdf/2002universaljointcatalog.pdf
or their website at http://www.neapco.com/index.
I also emailed SKF as their USA arm seem to have a loose connection with Neapco (supply them with bearings) to see if they stock Neapco parts, have other coated UJs or warrant my driveshaft against failure if I fit their steels. I haven't had a reply yet (only sent email sunday).
Numerous aftermarket suppliers say they fit standard steel UJs and I shouldn't worry. Most aftermarket parts catalogues also show the standard SKF part for both steel and aluminium drive shafts (and many show the two types). Any thoughts? Anyone have a aluminium shaft and had any experience with this issue?
