What Steering Box to Buy?

Blue Devil has done the trick in three of the trucks in my family. First was my eldest sin’s D1, then my 90 and recently my youngest’s. Much happier driveway and garage floor.

Jimmy for the 110, I sourced a local non leaking d2 box with the disco arm, and used a gywn Lewis conversion kit for it (2 replaceable ball joints)
Works great and no leaks... plus the used box was $125, the Gwynn Lewis kit was 200 something and a HD stainless bar as well with ball joints.

I must be the only one hat used Blue Devil and it made my situation worse. I added it and came out the next day to most of the fluid sitting under the truck.

I was lucky in my 90, that box never leaked. Just the hoses were leaking.

It works for me. Not sure what 1959’s issue was, but blue devil works for hardened seals—can’t fix mechanical issues or cracked/broken seals so won’t work for everyone... also, bears repeating—these boxes use trans fluid so use blue devil transmission version...

Im not a 100% on the condition of the box in my old Disco. It weeped before using the BlueDevil, but was made worse after. I also bought a bottle off amazon and read sometimes you can end of with counterfeit bottles. I looked on their website and they would only stand by buying it from licensed retailers. My buddy ended up replacing the box after getting the truck.

Isn't a D2 steering box different? I'd rather have one of those since they seem to not really leak.

There is one on the other side... and the steering damper but you right I need to add a nut to it. At the time I put it in it did not come with one.

Rob,
What did you buy from Gwyn Lewis to make the d2 box work ?
Never tried a d2 box but like the prospects of this swap

D1 and d2 are the same box.. just got it from mike sides... std 4bolt box with the disco drop arm.
I’m using this since I like the way the damper mounts better than the RTE kit + RN disco HD link I have on there does (it’s pin to pin vs the GL one uses the std pin to loop damper)


I’m going to put this one in this weekend (I got the SS version)

That looks like a Disco 1 box because it has the support for the pan hard rod. A D2 has a welded bracket on the frame for the pan hard so the steering box doesn't have the mounting holes for the pan hard setup that is on a D1/D90/RRC.

Do a hei while your there

I have one and wish I didn't. It is the only thing that has left me stranded in my truck. I'd much rather have the stock stuff and not have the factory harness hacked up to install the HEI distributor.
