5027 steve Posted October 30, 2017 Author Report Posted October 30, 2017 Ok I'm not understanding how to remove rear axles for seal replacement ...for what I'm understanding the hub can stay on axle and pull the whole assembly out????? What retains the axle then..Where is the rear axle drive shaft key?????? Head scratcher ...... Quote

Expand The "X" explains it all. Your truck was likely in the early transition... It got the updated parking brake, but not the column shift upgrade.

Expand Pull the rear brake drums/hubs, then disconnect and remove the brake assemblies, including the backing plates. The backing plate is the bearing retainer for the axle shaft bearings, and holds the outer seal. Once that is all removed you will likely need a puller to remove the axle shafts. The cup for the bearing is pressed into the axle housing. Once you get them out you can clean, replace, or re-lube your bearings. When they go back in the end play / bearing preload can be adjusted with the shims behind the brake backing plates. You need to have both sides in before making any shim adjustments. Quote

Expand Merle thanks and that's pretty much like our other Mopar axles....I guess 2 questions #1 why pull the hubs off and #2 what is the bolt that is at about 5 o clock behind the backing plate does that need to be removed before we remove axle????? Thanks again Edited October 30, 2017 by 5027 steve spelling Quote

Jerry Roberts Posted October 30, 2017 Report Posted October 30, 2017 " the bolt " You might be talking about a plug that is removed and a grease fitting installed in that location to grease your rear axle bearing . If you have a shop manual it should show it . On this location you have to be very careful not to over-grease as the pressure can push the grease past the seal and into your brake parts . That helps explain why mopar doesn't just leave a grease fitting in that spot , when the grease fitting is removed , the pressure is released and the new grease stays behind . Quote

Merle Coggins Posted October 30, 2017 Report Posted October 30, 2017 I've seen some that will argue against using a grease gun for this maintenance, which is called for every 20,000 miles. Instead they claim to work the 1/2 oz. of grease into the hole with your finger. This should eliminate the possibility of blowing out a seal. Here's a cut-a-way image of the rear axle bearing. 1 Quote

Expand So I take it the hub assembly has a key way in it????? Thats what's in the pic on the top......making more sense now pretty cool engineering on that port to grease the bearing....also now I see there is a inner axle seal and a outer axle seal ......to trap the grease between the two so the rear end fluid doesn't mix and wash out the grease ????? Am I thinking correctly ???? Quote

This must be done with both axles installed as they both rest against a thrust block inside the differential. Doing this adjustment with only one axle in place will cause the thrust block to be off center. Edited October 31, 2017 by Merle Coggins Quote
