Hi, I have a 1997 Jeep Wrangler TJ Sahara. I want to put manual locking hubs on both the front and rear axles. The reason I want to do this is because I frequently tow this Jeep behind a motorhome that doesn't have a ton of power. Sometimes going through the mountains its a struggle. If I have the ability to free spin all 4 wheels it would be easier to pull. I currently have stock axles (Dana 30 in the front and Dana 35 in the rear) but I’m open to swapping them out if that is what I have to do in order to have manual locking hubs. Is this even possible? Thank you for your help!
