Just repacked the bearings and replaced the inner seals. Question I have is about the ID. Napa crossed the seal to their part#17144 with the OD 2.565 and ID of 1.719 I just looked up the # on the old seal which is 174253tb and shows an OD 2.565 and an ID of 1.741. Is the replacement seal being 3/100ths of an inch smaller than the original going to be an issue? I'm guessing no, but need confirmation for piece of mind. 

.03 is sloppy .003 is alot better.  Seriously. 

Basically what you did was stretch the inner lip .022" to get it over the spindle.  That's pretty tight. 

A couple areas of concern I would have is the that much extra friction could cause the seal to over heat and burn the lip off or split, leaving you with no sealing ability.  Also, it could increase the wear on the spindle and cut deep grove that would make it difficult for the next seal to seal the axle and need a repair sleeve.

The question is, was the one you took out the OEM sleeve or one that maybe one that was wrong.  The sure way is to mic the spindle and see what it measures.  Then you will know what size seal you need.

And it could run just fine and not cause any problems.  That will take a few trips to the lake and seeing if your wheel passes you going down the highway in a month or so when the bearing fail from the water in them.

They were the original seals from when the trailer was new in 2013. A couple months ago I noticed one of the bearing buddies wasn't expanding when it took grease so I assumed it was blowing out the rear seal. Finally got around to it today and yes it was leaking out the seal as well as water getting in.  

Me being the anal perfectionist I am, and knowing the problems it can cause if the seal fails, I would have to pull it back off and mic the spindle and make sure what size seal it requires.  A couple thousandths ain't bad, but 22 is more than I would be comfortable with if it is in fact that much too small after measuring it..

 

Here's my standard procedure for replacing seals.  First, after cleaning everything, I mic the spindle/shaft, then look up the PN on the old seal and verify that number says the seal matches my spindle/shaft.  Sometime, with od ball numbers I have to do a search by using the OD and ID of the spindle/shaft to come up with a number, common problem when dealing with metric seals.  When I have the new seal, I do a test fit on the shaft before installing it.  After umpteen years of doing hydraulic work, I have a lot of respect of what problems the wrong seal can cause.
