hi guys,

anyone know whats causing this "leak", its on both sides under the rear seat. It seems to be coming from a round "pin" in the floor board under both rear seats, there's no dripping, just alot of moisture and its all over the torque arm at the axel.

see picture.

thanks for any ideas

If it's water, it's leaking in around the T-tops and coming out those drain plugs.

 

looks like the rear pinnion seal is leaking.

 

could be tranny fluid, rear end fluid or even water.

migt what to clean the area and then the next time it leaks you can identify the fluid/liquid.

 

whats a rear pinion seal?

thanks
john

 

If it's the rear pinion seal, it will leaking where the driveshaft's rear u-joint connects to the rear-end. Tranny seal will be coming from the driveshaft's front u-joint connects to the tranny. If it's coming through the floorboard, it's coming from inside the car--spilled pop, leaking t-top, etc...

 

the car has been garaged for 4 months +, i dont drive it, i work on it. trying to restore to showroom condition + some.
its a 92 rs /305 tbi/ auto the tranny was rebuilt/replaced with a gm reduild unit from a dealer 2 yrs ago. So it can't be water from the ttops .
