Dana Spicer 151 Boogie Axle Repair Manual

If you are pulling apart a Dana Spicer 151 Boogie Axle, you need the exact specs. I have seen too many guys guess on preload and wipe out a bearing. This Dana Spicer 151 Boogie Axle Repair Manual is the factory document – 52 pages of what you actually need. Page 1 shows the model identification: MO151B10. That tells you what you are working on before you turn a wrench. No aftermarket trivia, no generic instructions that skip the critical steps.

151 Boogie Axle Disassembly: What the Manual Covers

The manual walks you through the entire teardown. Starting with the hub and drum assembly, then the carrier, pinion, and differential. Each fastener has its required torque listed. You will find the order to loosen bolts and the specific pullers needed. For example, removing the bearing cap requires a different sequence depending on whether the axle is loaded. The manual spells that out. I have seen shops ruin a housing because they skipped the step.

What Torque Specs Are Listed?

Every threaded connection in the axle appears in the torque chart. The manual gives both inch-pound and foot-pound values for small fasteners like the inspection cover bolts and large ones like the ring gear bolts. No more guessing – you get the factory number. Use a calibrated torque wrench. If you don’t have one, get one. A stripped thread in a $3,000 housing is not a good day. Also note: the manual includes tightening sequences – not just numbers but the pattern and number of passes.

3 Reasons to Trust This Factory Manual

First, it comes from Dana Spicer – the people who built the axle. They wrote the maintenance schedule, the failure analysis, the tool lists. Second, the 52 pages were printed from the same plates used in dealer service bays. Third, the manual contains the original safety warnings. For example, page 1 warns about handling heavy assemblies and the need for proper lifting equipment. Aftermarket docs often omit those notes because they are cheap to reprint. This is the real deal.

Inspect the Bearings Before Reassembly

Bearing inspection is covered in detail. The manual tells you how to measure preload, check for pitting, and verify race seating. It lists the feeler gauge thicknesses and dial indicator setups. Do not skip this section. I have seen axles come back because the tech reused a bearing that looked fine but had a flat spot. The factory manual includes a chart with allowable wear limits. Stick to them.

Lubrication and Seal Replacement

Oil type, capacity, and change intervals are spelled out. The manual specifies the recommended lubricant viscosity for different ambient temperatures. Seal installation depths and tool numbers are given. If you press a seal too deep, it will leak. The manual shows the correct depth with a diagram. Also included: the breather service interval. Overlook that and you get pressure buildup and blown seals.
