Differential Seal Leak Needs Attention to Avoid More Costly Future Repair

Noticed during an oil change/vehicle check over, this video shows a failed differential stub axle seal leaking differential fluid. Without seal attention/replacement, the differential will eventually fail due to loss of lubrication. (The differential is a set of gears allowing a vehicle’s driven wheels to revolve at different speeds when going around corners. It is a necessary component for torque transfer and overall driving. Your car will not “go” if this system fails.) Knowing about this leak will save this customer from a catastrophic repair. Replacement of a differential system usually runs between $1,200 to $3,000 but can be avoided if properly maintained. It is uncommon for them to ever fail unless they are leaking fluid. A seal repair such as this would only run a few hundred dollars and topping off fluid before that repair would likely run less than $50. Make sure your technician regularly inspects the undercarriage of your vehicle so you are aware of impending repairs that will save you money in the long run.
