    Took the 96 3500 on a 4 hour trip a couple weeks ago, with the camper in tow. When I get home, I notice some fluid spray all over the front of the camper, back of the tail gate and bumper, and in the lh rear wheel well. First thing that went through my mind was rear outer seal, so I ordered one. Now I that I have time to work on it, I crawl under the truck to find the tire, brake assembly, and axle from the leaf pack out is dry. That has me ruling out the seal. Despite the red color of the fluid hanging from the underside of the truck bed and off the brake lines, I have my wife jam on the brakes. I know how brake fluid feels and thats not it. It also does not smell like rear end fluid even though the breather tube is in that general area. That leaves me with the thought that the shock had a catastrophic blowout. So I unbolt the bottom of the shock, it pushes up with nearly no resistance but requires about 100lbs of pressure to travel back down. Sound like a blown shock to you? I feel like such a cheep a$$ but I dont feel like replacing something that's not broke. And I need to return a $35 outer axle seal.

    Sounds like a bad shock to me. A gas shock will be real hard to compress and will extend out to max length on its own. The only other fluid in the truck should be tranny fluid, have you checked the transmission?

    x2 on checking the tranny fluid. When I towed to much weight with my 98 sonoma the trans would heat up pretty good and spray fluid out of tube on the trans. I just refilled it and it was fine for the last year of my lease.

    It was the shock. I unbolted both rear shocks to compare and found out both are shot. Nice, simple fix.
