Will GMC motorhome bearings fit the Toronado knuckles? Supposedly the only modification made to the Toro knuckle to fit onto a motorhome is to ream out the lower ball joint bore to accept the larger motorhome ball joint. There is no mention on if this is the big bearing that is used on the early knuckles, or the smaller bearing used on later Toronados. Perhaps someone who is more in the know than myself can tell. The OD on the bearing is 3.250". I do not have an early and late knuckle to measure to see what the difference is.

Here is what I found at http://www.appliedgmc.com:
