Re: T-case bracing?

Wouldn't bracing the rear diff be more effective instead of the xfer case?

The bracing i've seen/installed on those cars looks like that of a mini roll cage, lol. I was just concerned because I'm afraid mine will do the same. I wish I had a spare, but I don't.

We (3/S) run them (on the 5 speeds only) because we crack the aluminum housing. The gears for sure aren't the reason. If you don't have a brace and crack the case you can break some of the t-case mounting points off the trans and have the drive shaft fall on the ground. (only one person has done this that I know of, then braces became the thing to do shortly afterwards). The brace will keep things in place long enough for you to notice the leak and not destroy an trans+ t-case.

So after upgraded front housings were made some people stopped using braces. Then one of the highest power cars broke a mid housing, pushing the gear out to the back of the car. Then you run a brace with the front housing, or an upgraded mid housing as well.

However for a DSM, I haven't heard much in the way of housing failurs. Mostly the gears...

Re: T-case bracing?

I agree with Ryan, I think the T-case issue is actually the gears grenade and taking out the casing, versus on the 3s,it would split at a mounting hole/internal hole area where the metal is really thin. (9 out of 10 we saw cracked at this exact intersection of holes), and then leak fluid=mass carnage.

I would say look into what the big boys do to keep them in check, I doubt it is really a base. Maybe make sure the driveline is preloaded before you launch at 550+ft. lbs/torque +slicks, or specially made gears, etc.

I was going to use the zoobaz, even on the street.

Re: T-case bracing?

I just thought of a great idea! Transfer case Insulation! To keep the transfer case all warm and cozy. I can have my fiance knit (fabricate)up something, Then i wont have to worry about the transfer case fluids freezing, ive heard of this happening before, it destroys everything! lol poke.

Re: T-case bracing?

Heh, I love how even when Swifty asks a legitimate question he gets 2 pages of trolling like were still in high school. I noticed I also have a alum headed transfer case, Is there any rhyme or reason to which cases have cast head pieces and which ones are alum?

Re: T-case bracing?

22 spline t-cases are aluminum (Galant VR4), and 23 spline cases are steel.
