All bearings are not created equal for fit or durability, so we only stock first class, long lasting, Timken® Differential and Pinion Bearings for your Dana front axle. Timken® was and is a a major original equipment supplier of top-notch bearing components to Dana Spicer. Since I first started rebuilding Dana axles in the mid 1970's, I have found Timken® Bearings to be the most consistent in relation to the published dimensions of any bearing on the market which makes rebuilding an axle right the first time a WHOLE lot easier!

All 1973-1976 and some 1977-1980 Chevy Blazer, GMC Jimmy and Chevy/GMC 1/2 ton and 3/4 ton 4x4 trucks have open knuckle Dana 44 Front Axles. Many of these vehicles have full time transfer cases so bearing wear issues on front axles can be expected on higher mileage trucks. With a full time transfer case, both axles are always powered during operation. If your vintage GM 4x4 has over 150, 000 miles on it, there is a good chance that significant bearing wear may have occurred on your differential and pinion bearings. When you replace the bearings, do not forget to replace the inner axle shaft oil seals.
