Title: Sure looks wimpy - crossmember mount that holds both the tranny and tcase
Post by: Mike Phillips on March 04, 2008, 07:31:14 pm: Sure looks wimpy - crossmember mount that holds both the tranny and tcase

Is this all that's supposed to hold the transmission and transfercase in place?

To me it looks like the transfercase is just left hanging on the end of the tranny by 4 bolts with all the weight and pressure on the case where the 4 bolts go into the transmission to tcase adapter.

Just doesn't look very strong at all. Seems like there should be a tranny crossmember and a tcase crossmember for strength and rigidity.

This stabilizer bar looks like an GM Afterthought?

One end bolts to these two bolts

And the other end bolts to?

A: A bracket I fabricate and then either weld to the frame or bolt to the frame?
B: A bracket I need to locate on a wrecked Blazer and remove for my Blazer?

How do you guys handle this Micky Mouse stabilizer bar when installing newer running gear to an older truck?

My first major 4x4 used a divorced transmission to a 2 ton military transfercase and both the tranny and the transfercase had their own mounts and it was bullet-proof and even shell proof.

Makes me want to redo the entire thing starting with a short shaft auto tranny and then going to some other type of transfercase.

Sorry, it just looks so wimpy and fragile.

Ugh...

Post by: VileZambonie on March 04, 2008, 07:55:37 pm: I just posted this, those connect to the bellhousing and to the two bolts you have there.

Post by: red4wd on March 04, 2008, 08:01:21 pm: Mike...I merged the two topics since they were similar in nature.

Post by: Mike Phillips on March 04, 2008, 08:29:00 pm: So there's supposed to be another rod like this? Or just the one?

(http://www.showcargarage.com/gallery/files/1/tcaseSupportbar.jpg)

And this is supposed to mount one end to the transfercase and the other end to the back of the engine where the bellhousing bolts up?

Post by: Blazin on March 04, 2008, 08:38:30 pm: Just the one on the passenger side. From the two bolts you show, to a bell housing bolt. I have broken 208 cases before on rigs that don't have that rod. Cracks them right down the middle of the back half / cover.

Post by: VileZambonie on March 04, 2008, 09:10:16 pm: Yeah I was thinking about the newer models which have L&R hand strut rod supports. Yours only has the RH support
