Bad tire? Bad wheel bearing? Bent wheel? Bent axle?
Could be a right rear axle bearing going bad.
the problem is the axle bearing has gone bad and ruined the axle seal. the gear lube is held in the differential by the axle seals on each end.

it has no rear axle
Vehicles with front wheel drive have a straight rear axle meaning there is no gear housing in the rear axle. Vehicles that are rear wheel drive have a gear box in the middle of the rear axle to change the rotation of a drive shaft to turn the rear axle. If you look under a full size pick up truck rear axle you will see a large gear box (typically referred to as a pumpkin) in the middle area of the axle. That is the gear box differential.
It would be recommended to replace the rear axle bearings and axles when they are worn/bad. If the bearings and axles are okay, just replace the seals.
