Broken tranny mount after 4406 swap....what can be done?

[vroomzoomboom]

i think in the next week or so, i am going to get a mustang mount, and cut the cross member, and weld a plate into it. if i do it, i will snap some pics

Here's a picture of the Suspension Bumper I put in the Skidplate. Seems to be hanging in there just fine. I guess the real proof will be after some miles, and some wheeling. I did a 5 mile trail last night, everything was great.

So it's directly supporting the 4406? But you still have the trans mount still installed right?

My 4406 has been installed for a year and 4 months already and the trans mount still looks fine. I don't go off-road anymore but other than that, what else can ruin the trans mount?

 

[Kevlar7R]

Yea, the trans mount is still there. Yes, it is directly supporting the 4406. It lifted it up maybe 3/8inch, so I figure it's taking some weight off the trans mount.

that is a good idea. the only thing i wonder is will that bend the plate.

I had the same thought, but when I was working on the swap, I accidentally drove over the plate while backing out of the garage. Rather than bending it, the truck just went up an over it. So, I feel a little better about it.

I also figured if it does bend it, there are a lot of those out in junkyards. And, it's also just a skid plate. I'd take it off, hammer it flat, and put it back on.

The skid plate should hold up since the transmission mount is still there.

did you put suspension bumpers on both sides or on one side only?

Not sure what you mean by both sides (front and back maybe?) but no, I only put in the one. There are a lot of different bumpers available, this one was a pack of 2 off the rack at AutoZone. It seems to have absorbed a lot of vibration that was making it through the tranny mount.

here's what i did

ordered a energy suspension poly mount for a 93 mustang 5L with a auto trans, cut about 1 1/4 off the stock cross member, and welded a 1/4 plate onto the stock mount.

bolts are a little tight to the front of the cross member, but i still can get a socket onto it.

Great job, that's the way it should be. I hope that mount lasts forever now.

 

[Kevlar7R]

That looks great!!! I may have to do that.

I did a 20 mile rough trail this weekend. Everything performed great, however, the bumper in the skidplate squeaked. It was a little annoying.

Well I've seen how Kevlar hasn't been online since last year but anybody have a clue where to get a suspension bumper for this application? Any info would be nice to know so I have EVERYTHING I need when it's time to FINALLY do this project. Thanks.

something tells me that is/was like a hood bumper from the ford highway tractors (like the aeromax, or LTL 9000's). then later became sterling trucks. i can almost bet if you go to a heavy truck dealer, and show them that picture, they will have something like that

Looks like an aftermarket rear bumpstop to me.

 

[gmanpaint]

Daystar, Energy Suspension, and more make Bumpstops. Plenty of places sell them.

I wouldn't do something like that with the bolt hanging so low under a skid plate, but to each their own

 

[Steeda04SVT]

Good info. Thanks guys for the heads up.

You could always drill the hole and mount the bumpstop but instead of putting a nut on just weld the threaded part to the skid plate and grind off the extra

Since my skid plate is actually 2 of them doubled up and welded together, I am going to drill and tap a hole, then cut off the excess.

A little loc tite and gravity will hold it there I reckon. we'll see.

My Low budget attempt #1

First, I needed a spacer of some kind between the transfer case skid plate and driver side frame to clear the 4406. I used 2 torsion bar adjuster plate nuts. I also had to do some clearance grinding which you can see in the picture. This yielded less then 1/8" clearance when bolted up tight.
Doubling up the 2 skid plates required re drilling the bolt holes, which I enlarged to accept 3/8" bolts. I used a tap to cut threads in the skid plate bolt holes in the frame and drove the bolts in from the top. The threads hold the bolts still for hanging the skid plate. :smoke::smoke:
Then with the skid plate hanging as low as possible while still being suspended by all the bolts (nuts), I Jacked up the t case which opened up a bit of space, into which I forced a door bump stop in between the 2 square tabs on the t case and the inside corner of the skid plate. I also shoved a shock absorber bushing into the center over a tiny hump in the t case casting. Then I bolted the skid plate up tight and let the jack down. Everything compressed down pretty good. Gravity and tension alone holds them in place, even after several accelerations from stand still in both reverse and drive. Now there is at least 1/4" clearance all the way along the skid plate, so I know the t case is supported a bit by the "new" pads.
