I have a '66 f100 step side long box 352 auto. It has the 3 piece drive shaft. I'm replacing the U Joints and want to do the drive shaft bearing at the same time. I'm ordering the parts from LMC truck. According to them, there's two drive shaft bearing sizes. One with ID of 1.378" and one with ID of 1.5478". Any idea how I check the ID of the bearing without removing the drive shaft. I can't get at it to measure it as there's shrouds around it that prevent me getting the vernier at it. The spline shaft on the back side measures 1.375". Should I assume that the bearing ID is the 1.378"? Any insight would be appreciated

Why buy parts from LMC in KS and pay shipping charges when you can get them locally from NAPA & etc auto parts stores.

 

I'm putting through an order with LMC for a bunch of other hard to find body components, so was just throwing in the U joints and bearings with the box. Other wise... completely agree local guys are where to go!

 

Make sure you get the correct u-joints, LMC usually doesn't have a clue inre to mechanical parts.

The shipping charges might be cheaper if buying the parts from Mac's Antique Auto Parts, since they're located in Lockport NY.

 

Why buy these parts to places like macs or LMC. Where do you think they get them? Drop shipped from Rock Auto or NAPA with a markup.

These are still readily available.
