I also have this posted on the Falcon board but thought others may have run into this and might have a fix.

'68 falcon, stock spindles & hubs, new bearings & races. Problem is that the flange on the inner wheel seal contacts the face of the spindle before the inner bearing contacts the bearing stop. The result is that the wheels are extremely hard to turn. I pushed the car from one side of the garage to the other and when I disassembled the hub I could see rub marks on the seal flange.

Parts are correct per application - Inner bearings are a Set 6 (LM 67010 race, LM67048 roller) and the seals are 6715. National seal, Timken bearings.

I've been a Ford guy a long time but have never seen this problem before. It's almost as if there is a 1/4" of material gone from the bearing stop on the spindle, but there is no real evidence that this is the case.

Has anyone run into this before? How did you overcome?

I should point out that I have no idea how this car ran and drove as I purchased it w/o motor or trans. This is a bracket car project so I just automatically started replacing everything. And yes, the parts do match the old ones.

Thanks for any assistance.

Is there any chance the bearing hub is the wrong one? That sounds more like the problem putting the seals and bearings in the wrong locations. Could be a previous owner changed them and just used whatever they could find.

Thanks for the response. I suppose that is a possiblity, although everything else appears correct. Outer bearings fit fine, brakes, etc. I'm not sure how many different 5 lug hubs Ford used back then. I do know that the V8 Mustang hubs are the same and call for the same bearings & seals.

Quite the puzzle.

Update:

After taking everything apart I have found that the seal is actually rubbing on the rasied center portion of the backing plate, not the spindle face as I first thought. With the backing plate off of the car there is plenty of clearance for the bearing and seal.

Unless anyone can think of a good reason not to, my plan is to grind down this raised area, hopefully without altering the size of the opening so that the plate can still index onto the spindle. The four bolts that mount the plate to the spindle will also help to index the plate.

Thoughts? Cautions?

Update to the update:

Problem solved. Trimming down the rise in the backing plate did the trick.

Still don't know why this became an issue. I will be monitoring these areas closely once the car gets out and makes some passes.

Thanks for your responses.
