Question for the group. The service manual list those two RPO axles as SERIES 20-30 5200 AND 7200 LB capacity axles. Then they list a Series 30 11,000 lb axle.

The 11,000 lb axles has the pinion supported by ball bearings instead of tapered bearings.

Am I to presume the H072 is the 11,000 lb and the H052 is the lesser?

The service manual also shows threaded holes for removing the axles in the 5,200-7,200 and a slide hammer necessary for the 11,000 axle shafts.

My original axle is long gone but the door tag list the GVRW as 7500lbs. This Suburban would have had a H052 or H072?
