Get it repaired, of course.
IF you have rear wheel drive it may be a grease seal for the rear differential. Otherwise it is probably a wheel cylinder. Check your brake fluid level. GEt this fixed ASAP- Safety concern. Wheel cylinder, brake fluid.. If it's a rear wheel drive vehicle, it may be the axle seal leaking as well. Hello... hello...
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.
how do you replace a Ford F150 rear axle seal
not sure what kind of axle you have and where its leaking. are you sure its not the brake fluid leaking which is above the axle seal to make sure that's not the problem which is easier to fix. as for the axle seal on the chevys the axle would have to be pulled out which means pull the rear cover off and taking the lock pin out pushing the pin out and then remove the axle ring then you can pull the alxe out. that for a solid axle. if you have an independent then you would have cv axles in which case they have wheel bearings and then it would be the brakes leaking. wish you had more info.
Leaking brake cylinder (or caliper piston if it has rear disc brakes). Also if its a rear wheel drive vehicle it could be differential oil leaking from the outer axle seal. If its a brake fluid loss you can monitor the fluid level in the master cylinder .
You will have to first find out if there is a hole in the part. If there is, then you need to get it replaced.
It depends on the seriousness of the leak. Basically, if you car is not in top condition/repair you should not drive it.
your main oil seal on the rear of engine is leaking or the timing cover seal is leaking,
It all depends on what part is leaking what fluid. Brake cylinder would leak brake fluid. Axle seal would leak gear oil.
Remove the tire and wheel from your 2003 GMC 2500 Sierra. Remove the end of the axle. Using a seal puller remove the axle seal. Reverse the process to install your new rear axle seal.
NO... They are 2 different seals. If the transmission seal is leaking then the fluid color will be RED that's leaking. If the rear main seal is leaking then it will be oil leaking from the engine and it won't be red.
