I was under my car today, adjusting my tips, and look back to see that my TQ Arm was covered in gear oil....now I'm worried....I looked in my driveway and saw two descent sized oil mark from where it was dripping off the bolts....now does anyone have any ideas? I hope it's nothing serious...

 

Yeah this is the leak at the pinion seal.If it is leaking bad enough to drop on the ground you need to get it changed out. Might as well get new gears in the process. Id keep it topped off until you fix it.

 

I also believe your pinion seal is leaking. This is a common problem with the f-bodies.

 

I already had my gears done....now I'm pissed....cause I had the dealer put my gears in and could they mention the seal was shot? Of course not....

 

Everything leaks from the pinion seal but having the driveline
angle off, really aggravates it when the shaft is turning at
high speeds; U-joint vibrates the yoke more and kicks the seal
off seat. If you bias the pinion angle for launch but do not
keep the driveline angle right, too, then you may cruise with
a lot of vibe at the back (whether or not you feel it or ignore
it) and compromise seal effectiveness even if the seal is not
"bad".

To correct driveline angle, once you have the bite dialed in by
torque arm angle (pinion angle is said, but it's all about the
TA - LCA geometry for bite and the driveline net angle for
vibration, pinion angle is just stuck in the middle) you may have
to play with the trans tail angle - shim under the trans mount
to raise or the two crossmember mount points to lower the tail
and bring driveline net angle closer to zero, accounting for any
windup at load (cut and try basically).

Seals do wear of course but having this show up post-TA is
suspicious.

 

Well my car always had a slight leak from the rear....but now it's really leaking perfusely....
