95 chevy suburban auto. leak Sign In

It's my nephews 95 subarban mini van work truck with side and back doors , with a 4.3 and 178k on it , trans fluid is dripping out the tail end of the trans where the drive shaft enters , looks like a seal could be replaced at that point but somehow I don't think it'll be that simple and that there's something internal that might be the problem ,we're going to check it out when it stops raining , any thoughts or suggestions ?

That's interesting. Have never seen a suburban with a 4.3L in it. You sure this isn't an Astro or Safari van?

Worn tail house bushing or slip yoke can cause leaks if the seal isn't the issue.

Agree - I doubt "Suburban" even made a work version nor the 4.3 so just a smaller one as DS mentioned.
No matter I think you are talking about seal at slip yoke shaft. IDK - particularly if shaft for any reason is pushed in farther than it normally travels as in removing driveshaft or maybe a heavy load it probably would tear up that seal like a grease seal for serviceable wheel bearings can be replaced. Lube that end of driveshaft with a smear (just a tad) of grease for installation and probably already lost index the rear yoke as it should be balance for one position but fits either way- mark it,

No , it wouldn't be a suburban would it , I'll have to check that , I wrote down what I saw , he just stopped by and says it's slipping and banging back into gear but fluid is at right level ,but it's hearsay so I don't know for sure , sounds like big trouble ,

You could replace just the seal but with the worn bushing will likely ruin the new seal in short order.

Hello,
Those bushings do wear out, see if drive shaft has play. Gary
