240 differential pinion nut torque
I just replaced the pinion bearings in a 89' 240 wagon. The book calls for a pinion nut torque of 148 - 180 ft.lbs. When I torque to this spec. the pre load is way too tight. I used blue locktite on the nut, and tightened to about 40 ft lbs to get the desired bearing preload of 2 ft lbs. Is there something I am missing ?? I used the old nut,and new bearings. When I disassembled the pinion, it took at least 200 ft lbs to break it loose, and I made a reference mark on the shaft and nut. Now my reference mark is 1/4 turn away,and the pre-load feels ok.

The pinion bearings,and wheel bearings. The differential carrier bearings looked good. I set the preload at 25 inch pounds, which felt a little tight. The specs. I found searching the internet. Even though the axle parts are all stamped Volvo, several forums say this is a dana 30 axle,same as the CJ jeeps ? The Bently manual has no differential specs.

actually, there's several complete greenbook on rear axle repairs.
http://www.k-jet.org/files/greenbook...le_repairs.pdf is one.
and, on page 15, sure looks like 150-185 ft-lbs if its installed correctly. or 175-220 ft-lbs if you got that one version.
