Default Differential Oil Leak

I have a left-side differential oil leak which drips onto the floor occasionally, especially when it's hot. Should I spend the money for the dealership to fix the leak, for which they want about $600? Or can the leak be sealed from the outside, with a special gasket sealant? Any thoughts would be appreciated!

I also have a related, but ignorant, question. If the dealership fixes the leak, does it make sense to replace a noisy clutch at the same time? I'm not sure what part of the driveline must be removed to fix the diff leak, and whether the clutch will be exposed in the process. Thanks!

Default No quick fix

I see by your profile that you have a 2000 coupe. If this is the original clutch, I would have both seals (left and right) and clutch installed at the same time. And no, you cannot properly fix the left side diff seal w/ a sealant from the outside of the diff. Good luck.

Thanks, Bumble. Regarding the clutch, would it change your mind if I mentioned that the car only has 28k miles? The only reason I mention the clutch is due to a rattling noise when going into first. But I'm not sure if the sound is from the clutch, since it continues for a brief moment after the clutch is engaged and it never occurs between other gears.

You may need a clutch @ 28K mi. It all depends on how those miles were put to use , in regards to proper clutch ingagement. Such as racing, feathering the cluth at lights,stop signs etc on steep grades.Someone eles driving the car that is not fimiliar w/ manual shifting. There are alot of varibles there.Good luck.

Okay, so does it make sense to replace the clutch with a stocker or buy a higher performance clutch? Some of my driving is in stop-and-go traffic, so I don't want a clutch that is too difficult to modulate.

I would go high perf. Just in case you get the mod bug later- you don't have to do the job twice. Being proactive. Most AM clutches have very drivable pedal pressure. Just do some research on a few diff ones to find the right one for you.
BTW- both mine leak from the diff too

If your not going to be racing and your not beating on your drive train, a stock set up will be just fine.
