I am installing a 4.5" Maxtrac spindle on my 02 ram this week. I currently have a 1.5" coil spacer on the truck, but that is coming out when the spindle gets installed. I am also planning to replace all my ball joints when I get the spindle lift installed. I bought moog greasable upper ball joints, but I am torn on which way to go on my lower ball joints. I have had greasable lower ball joints in the past and the boot always finds someway to get torn. Would it be smarter to go with a sealed lower ball joint? What are your opinions?
