I would like your opinon regarding the modern drive shaft pinon bearing assemblies with tapered roller bearings and offered by Lang's. Are these better than the original type Ford assembly from the factory? Lang's states that it eliminates all drive shaft end play. Just thought that I would ask the experts out there who have more knowledge than me regarding this subject. Thanks, John
I have two of John Regan's (fun projects) and I am happy with them. Don't know who makes them for Lang's.
I have found these to be a great upgrade.
You have the benefits of a better / stronger bearing taking the load of the pinion being forced out of the differential by inner forces and the second bearing takes the driveshaft load coming from the other direction that is usually taken by the upper bronze bush at the universal joint. Once installed the need for setting the shaft endfloat via machining the bush face is eliminated. John Regan advised me to purchase the standard unit (not shim type) as it wasn't necessary and he was 100% correct. Word of warning, leave the top bronze bush (uni joint end) as is and forget any changes to a torrington needle bearing.Go for it.

Check out the one from John Stoltz, one of our members really likes them. They are x-y adjustable.
