Hello everyone. Would anybody know were or what company makes those Axel saver offset bearing for the safari-Astro's.

Most every auto parts store carries them in stock, very common item. After the part number on the box, there's usually an "R" meaning that it is a "repair bearing".

Thanks i found them Old_Master. Just off Topic I replaced them because i had a whinning noise in the rear Diff. Old ones seemed fine so i took a chance maybe the inner race or something was bad. Iam back to squre one. same noise after replacement. Are the pinion Bearing a problem with this truck? Maybe you can give me an idea if its a common problem. raisung the vehicle and running in drive noise is not present but above 20klm noise returnsright up to 100klm even beond but i guess road noise hides abit of the diff noise.

It depends when the noise is most pronounced: light acceleration, maintaining speed, or coasting. If it produces a "whine" sound, usually it's caused by wear in the ring and pinion gears. Improper set up or normal wear can both cause it. If the noise changes pitch when quickly changing lanes, it's more likely to be a wheel bearing, although they can also be noisy just going straight as well, producing more of a "growl" noise.

Thanks old_Master. The noise is more of a graoning sould ubove 20klm. and is constant regarless of turning or load shifting on left or right wheels. ring gear and pinion were inspected when i removed the cover and removed the c clips. (No abmormal wear on ring gear or pinion.

Could be pinion bearings. Have to use a stethoscope and listen to it.
