98 Expedition 5.4 4x4 250k miles.
Problems. I heard a slight grinding noise and vibration at higher speed (above 40 mph) that change with speed, not RPM. Goes away on one turn, stays on the opposite turn. (I don't recall which was which). I inspected the front parts and determined I need a new upper control arm ball joint on passenger side, that is for sure.
The boot on the passenger side CV axle is broken completely. It is a remanufactured Duralast that is about 5 years old. Lifetime replacement warranty, but they don't offer remans anymore, so it will cost about 50.00 difference in price to get a new Duralast.
The drivers side is not making any clicking noise, but seems to have a little play when twisting shaft not a lot, but some. It is original with about 250k on it.
I am not sure if some play is normal or not.
1) trying to determine if bad upper ball joint could cause the vibration and slight grinding noise while driving, or if cv axle(s) could be contributing as well.
2) Is it better to rebuild the original CV axle on driver side, leave it until it starts clicking noises, or replace and if so, replace with what brand?
3) Rebuild and/or re-boot AZ axle, or get a replacement (50.00). If rebuild, where to get rebuild kits
