Steering Column Firewall Gaskets

I guess this is what I signed up for when I bought a Bronco instead of a K5 Blazer, I rebuilt my steering column and now I can't mount it until I replace the firewall gasket somehow. But it's not an available part so I have to get creative.

I searched up a recent-ish thread regarding peeling back the rubber and sticking it back on. Well the rubber on mine was toast so I came up with 35% of the solution. Possibly.

I have tons of EPDM rubber left from making my custom firewall insulator and I made an outer gasket. It would probably work but it's thin and combined with the billet lower column bearing it will transfer extra vibration to the steering wheel. I will either triple up the gasket or just get thicker material as I still have my template to make more.




Okay now I must find something that seals the column itself. There are similar gaskets available for dentsides and I'm wondering if they will be a similar diameter.

Nice job but I think you are over thinking this, it's a truck not a Cady

I dont remember what shape mine was in when I put it back together and I dont remember any air leaks from that area.
I dont think there is a seal between the tube and clamp from what I remember?
Also if installing a rug it would cover that area and also stop any air leaks.

There is a center seal component to the rubber boot that is moulded over the whole mount. I believe it doubles as a vibration damper. I'm thinking I might have to do this in 3 pieces but we shall see what I come up with.

I bought a large silicone grommet that will go between the column and the firewall mount and it should fit with trimming. And you are right Dave, the clamp goes around metal. The seal is on the mount itself and is moulded around that raised lip in the center. I'll post pictures when I get it all together.

Silicone grommet did not work. I cut it down to size and it would slip out when I tried to tighten the clamp. I think I will try some kind of hose for a damper and then use a roof vent pipe seal as a boot.
