Going through the steps putting the BW4406 manual shift in my rig...quick question, if it's been answered before, I'm sorry. Did a quick search and wasn't able to find any info. My question is this. I have an abundance of 75w140 oil right now, and no 80w90. Is it going to hurt anything to run 75w140 synthetic in the front diff? Thanks in advance for any answers/info.
