Fits my 1994-95 Ranger Trail Trailer

I have a 1995 Ranger R72 boat, purchased in the fall of 1994. The right/starboard hub-rotor got a crack in the rotor and I had a difficult time locating a replacement. Ranger (now Bass Pro) said it would take 12-16 weeks and a special $300+ order to have a new one cast for me. After a lot of searching I found this one at Pacific Trailers. My hub-rotor has the same size bearings (L68149) for inner and outer and an EZ lube #84 spindle. This UFP hub-rotor is a perfect fit with the exception of the grease seal. You need to get the "Trailer Hub Grease Seal For 1 3/8" L68149 Inner Trailer Wheel Bearing 168255TB" as well. I got 2, one for a backup in my parts box along with extra bearings. This new hub-rotor has a larger diameter seal opening at the inner axle but the bearing is still the same.

Perfect fit

Trailer is 22 years old wasn’t sure I’d be able to find the oem parts. Pacific had exact parts at the best price.

Seems to be OEM specs. Lined up with my bolt pattern on my ‘02 Ranger Trail. No play once completely installed. Races included.
Not sure if it was the bearing buddy or the hub/rotor manufacturer but someone’s quality control was lacking that day. Pain in the stern, pun intended, to “tap” on the bearing buddy.
Not Pacific Trailers fault. They are great, helpful, and I’ve already ordered more parts from them since ordering this hub/rotor and bearing buddy.
