Steering Gear Box leaking. . .

[madslammer]

Last week I installed an Overland Vans' 2" lift block kit on my 1987 2wd Astro.
It all went well and looks great, but a couple of days after this the steering gearbox started leaking fluid from the top seal area. I had noticed that the steering felt kind of hard, but i thought it had to do with the lift and that was a normal condition. Then the steering sudenly felt lighter again, and that day was when the leaking started. I tried a "miracle" leak sealer that the auto parts guys recomended and that made the leak worse. . . #-o
Not sure but at first I thought the body might have moved a little more to one side than the other. The van is running straight, no vibration, no strange noises, etc. . . .

Anyone have had this happen?
Thanks.

My steering gear unit only leaks out the top when I remove the cap off the fluid reservoir.
Barely drips a drop otherwise.
Take the cap off to check the level and there is an 18" puddle in less than 2 hours.
So ... I don't take the cap off anymore.

Don't know if this is your problem but hey ... any info is usually useful info.

What does the kit you installed do to address the 2 inches of extra length the steering shaft would need to make up for the lift? Usually on GM products, there are nylon inserts in 2 channels on the rod, that allow for the steering shaft to "collapse", in case of an accident. My best guess from your description is that nothing was done to address this problem. The simplest solution would be to apply heat to the steering shaft where the two nylon inserts are, causing them to spew out flaming hot bits of nylon, but allowing the shaft to be extended to the proper length needed to reach the box with the proper angularity of the U-joint at the top of the box. After you fix this shortcoming, some stop leak may help with the fluid loss, but as it stands now, the input shaft is wobbling around in a funny ovalled shape as the joint comes closer to each apex in the U-joint. Centered shafts should put equal pressure on the seal at all sides all the time, fixing the problem.


Maybe.

And it could just be age. Rather than trying the bandaid fix you'd be ahead of the game if you replace the seal.

Man, that seems to be the problem. We did the lift and the steering shaft extended about 1 1/2" but when it goes around looks fuuny. I have to check again to make sure it's still doing that "wobbling", as I said, the steering felt hard but then it started feeling better. Maybe the inserts broke or something like that. Do you have a pic of where the insert are, 'cause i have no clue. I might give this a try, 'cause I have a spare gear box and don't want to break that one also. . .
Thanks.

That could be a reason also, I have a spare steering gear box, but I need to be sure before I install it. It ain't easy to find spare parts here anymore. . .
at least at reasonable prices. . .
Thanks.

my van is buried under almost 2 feet of snow at the moment, maybe someone fron a warmer climate with their grille or fender off can snap a pic for you? Sorry.

Man, I love the Tropics. . .the sun, the beach. . .
Now seriously. . . I meant a pic or a illustration of where these plastic parts are located on the steering shaft. . . so I know where to look. . .

UPDATE! ! ! !
I took a look at the steering box last night and there was no oil around the top seal. No oil spots on the floor, either. :-k So, I took it to the club meeting and some of the guys that usually work on my vans looked at it and there were no leaks found. The fluid level in the reservoir is ok.
I left the van at home yesterday and took the 97 to work, I figure that by letting the van at home the remains of the sealant did their job and stopped the leaks. Anyway, the steering shaft's rotation seems fine, no weird noises, no vibrations. . . I think we can call this one. . . DONE!

Well, it's leaking again. . . ](*,)
Not as much as before, but it's leaking from the top seal area. . . Again. . .

There are seal kits available. It's not a real hard job. Bite the bullet, man. And you'll have a great feeling of accomplishing something.

I guess I'll have to give that a try, then. . . [-o<

Was curious how you made out with your steering problem? I'm having some issues with mine.It steers real hard,doesn't seem to be leaking either! :-k
Thanks, Bill

Thought I would drag this out. I hit a curb after following some guys that tried to steal my wife's car after pitting them off the road. After pointing out to the police which way they ran off and letting them chase them down. I got back to my Astro to find a big chunk out of the rim and the steering wheel twisted 30* off. I thought I just knocked the steering linkage out and I would be doing some adjusting to the linkage. The next day I came out to a puddle of PS fluid in way drive way. I was like great. So I ordered the seal kit and will be changing the gear box seal. I just finished rebuilding the front end on my 01 Blazer. Well once I'm finished with this project Ill post how it went on here. Hope it won't be a PITA.

Good luck! Check your wheel bearings too, you might find one is now loose causing the steering wheel to be off.
