QU50630 Timken Taper Bearing used for Wheel, Diff, and Transmissions

QU50630 Timken® Tapered Roller Bearing is used for many different applications including IHC or Jeep 4x4 front wheel bearings, Ford differential side bearings, and transmission bearings but the most common 4x4 specific application would be as an inner front wheel bearing on 1976 to 1986 Jeep CJ 4x4 front drive axles with disc brakes. This is a First Class, original equipment quality bearing that meets or exceeds all vehicle manufacturer specifications making it the top choice for heavy-duty applications like yours. Country of origin may vary as Timken produces Bearings in plants located around the globe, however, QU50630 is almost always made in either Canada or the United States.

Applications

Tech Note 1: Matching Cup 
Always replace the cup and cone at the same time. The matching Bearing Cup is QU50629. There is also a high performance version of this Timken Bearing used as the countershaft front bearing in New Venture NV4500 5 speed manual transmissions, see QU10142.

Tech Note 2: 1959-1996 Ford F100, F150, Bronco 9" Rear Axle
In May of 1970, Ford made an engineering change to the 9" truck rear axle. Effective with trucks produced on May 11, 1970, MOST 1970-1972 and all 1973-1986 Ford 9" rear axles axles will use QU50630 1-25/32" ID Differential Side Bearing and QU50629 2-57/64" OD Differential Bearing Cup. Previously, Ford built a standard 9" with 1-5/8" Cone x 2-57/64" cup and a heavy-duty 9" with 1-25/32" cone x 3-1/16" cup.

Tech Note 3: Wheel Bearing Lubrication 
Front Wheel Bearings MUST be fully packed with grease before installation. This means all the voids between the bearing rollers must be filled with grease and the contact areas of the rollers along with the matching bearing cup must be covered with a film of grease. Always use, new, quality, clean grease to pack bearings. For most applications, NLGI#2 EP rated grease is recommended for Wheel Bearings. Disc Brake applications also require the grease be approved for Disc Brake use and/or have a high-temperature rating. Use of Bearing Packer QT5500 is recommended.

Tech Note 4: Differential or Transmission Bearing Lubrication 
Prior to installation, lubricate differential or transmission bearings and cups with the same lubricant as will be used to fill the unit. Use only new, clean oil approved for the differential or transmission being serviced. 

Tech Note 5: Differential Bearing Installation
When pressing QU50630 second differential bearing on the carrier, support the differential with QT1035 Step Plate to prevent damage to the first bearing.
