04 Front Dana60 question
Does anyone know if i can just use regular gear oil in my front axle?? trucks driving me nuts with the whine/howling/hum every time i have to lock the front in.. Book says not to use anything other than 30w gear oil.. but wondering if i can just clean it out and use 80w90/140 or 75w90/140..

im thinking its either not being lubed enough because the oils so thin or the R&P's not set right.. i know both can cause the same issue.. but wanting to try the cheaper thing first before taking it somewhere to have the front reset..

Put some STP in it.

It's R&P alignment, the heavy oil is just a band aid.
