Put in a new passenger side front CV axle yesterday. The boot was torn and with the axle being the original piece with 89,000 miles on it might as well just swap it out for a new one. So for the record that's 89,000 miles on the truck (68,000 with a 2.5" lift and no differential drop) and I've swapped a speared inner boot on the drivers side with a new boot at around 40,000 miles (what a PITA that was), replaced the drivers side front CV axle with a new unit at 75,000 miles and now the passengers side is R&R'd at 89,000 miles. Not to bad as with my old Dodge I had to replace the front hub bearing units on the solid front axle every year. Man, those 1st generation Rams ate HBUs like M&Ms not to mention doing the same with front brake pads.
