Default Trans cross member ?s PICS ADDED

I built a new trans crossmember that has the trans bolted solid to a 3/8" plate. I then have tubing going out to the frame. I fishmouthed and welded a couple of pieces of pipe in a "T" that some spring bushings I had laying around fit in. Welded a couple of tabs to the inside of the frame. bolted the bushing part of xmember into tabs on frame.

So great, I now have a pretty flat belly on my Jeep. Now a guy at work that I showed my xmember to said " is that going to flex enough? if not you might crack/break your trans case "

I was really happy about my work, until the guy said that. So now I am worried about that. Has anyone ever done this before? I swear I have seen a factory xmember like this on a Ford before (mustang, ranger??).

I will try to post some pics later.

Thanks,
Fred

I run a t-case crossmember which is rigidly bolted to the t-case. I use rubber bushings at the frame.

I've never busted mine, but it has happened to some.

Any pics?

Depends on your trans, power, and reduction really.

This setup cracked the case on my cast aluminum AX-15.



I gave up on trying to fit a separate cross member and skid plate in my YJ. Now I have my trans mouned to my skidplate stock style.

I used some OEM style impregnated rubber bushings. The kind you see in control arms and such.

This isn't mine, but mine is similar:



I think why it works well on the toyota stuff, is that their are ~10 bolts of attachment on the back, so its spread out. Likewise, the transmission to transfer case mating point is large and strong, not the typical neck down with the round NP/NV/Dana style t-case.

the thing i dont like about the bushigs being so far out from the case is they dont give much, yes they still absorb the vibrations but it doesnt allow for much if any roll deflection.

I guess it comes down to preferance and experience as to which way you do it.

I've made my own on a couple vehicles and always used the stock mount to keep it simple. But that was me just being lazy and not wanting to hunt down bushings for the outer sides

Here are some pics.

The reason I did this....

Nice flat belly!! (unlike me )

Pics of the xmember




I am using poly spring bushings. I'm sure the're a little stiff. I thought that I might grind out a quarter of the bushing above and below the bolt to make it a little more flexible.

As for the other questions monkeyevil asked, its a CJ7/304/NV3550/stock D300/4.56 axles/ on 35" tires. Its my daily driver/trail rig(once or twice a year).

Thanks for the replies and keep them coming. Next I'm building my exhaust to continue with the hi clearance theme.
