<IMG SRC="smilies/biggrin.gif" border="0"> I did the search <IMG SRC="smilies/biggrin.gif" border="0">

I did a 3" body lift and also lifted the motor 2", I was going to make my own cross-member but after looking at it more and looking at the ones from FROR and Budbuilt I have some questions.....

1. Can I use a dual case cross-member with only ONE case??

2. I'm thinking that the FROR might be stronger(?) because it dosnt use the stock rubber mount and mounts to the case... BUT I like how the Budbuilt looks...

3. Has anyone made there own cross-member and have any pictures and/or a good description of how they made it AND are you happy with it??


Thanks
Oh ... it a 84 4runner

Hi Kyron,

Great to hear you're making progress on the toy.

I made my crossmember out of 1/2" plate; cut, formed, gusseted and welded. Really strong and after lifting the drivetrain 1- 3/4", almost flat between the frame rails. You can countersink the mounting hardware if you want. I used an OEM mount under each X'fer. They are plenty strong and cheap at the boneyard.

I don't think my design will work with a single case, but I've never measured to see.

I should think so, since the front case is in the stock location. You might want to contact Bud and ask.

Hey Kyron,

I have a Budbuilt on my 80...

I dont have dual cases yet, but Bud made me a dual case member. He made 1/2" spacers to go between the member & tcase mount, & between the member & frame......Thats the only mod MINE needed.......You'ld have to contact Bud to see if he could do the same for you....

Basically the drain plug hang area hangs down almost 1/2" lower then the bottom of the tranny mount....

They're just temporary till I get a dual case.........

But then you might need longer bolts to mount the member to the frame.....

I swapped trannies, & my xmember location changed, so I couldnt use the stock location. Mine is supported bu U-bolts over the frame.....

Update time :laughing: I completly forgot about this........

I ended up getting a Budbuilt and doing dual cases at the same time ........


all was well for 5 years untill I tore the 4runner apart to build a "buggy" and saw that one of the cases broke..........

the other case mount is still in good shape and the bolts are still tight


What should I do ?

The motor mounts are stock and chained (pretty tight too)

I'm thinking about keeping the Budbuilt xmenber then add a FROR mount to the back ??




Any thoughts ........

Get a new case....
I'd rather not break them apart

Time for some HD tcase mounts from 4xinnovations?
thats what I was thinking BUT for the same price as the HD mounts I can buy the FROR face mount and some YJ bushings... then keep the remaining mount (and a half:laughing:) on the BudBuilt .... basicly have two diffrent t-case mount stlyes at the same time?

Adam from 4xinnovations claims you only need to run one of his mounts, and they were on sale last time I checked. Marlin crawler also sells his mounts, and Trail Gear copied him :)

I would agree that only one is needed. I have had a 4xinnovations heavy duty moutn on my truck for a couple years without problems. Check this out for a little more info.

I have a FROR x-member right now and for the most part love it! There is no more movement side to side under heavy torque. I use to get a side to side "twist" when I was in dual ultimate low and came up against a verticale obstacle. I believe this movement was helping waste the motor mounts prematurely. This was with a stock x-member and mount, also some of the problem, I know. Now that I have the FROR I have not had any motor nount issues at all. I do have a slight forward to back movement when I get into a certain speed, like third gear, stock low, cruising down the flater parts on the trail. I am thinking that I am going to add some BudBuilt type "wing's" off of the skid plate up to the frame for more support and hope to get rid of the forward movement. My only concern is that this will direct alot of vibration into the chassis/cab as there is no rubber mount on the skid plate. Givin that mine is strickly a trail rig it wont bother me, however some one who DD's there rig may not like this option.

That's an unusual break. My first suspicion would be that the bolts on the other side were missing (were they?) and that put all the torque for that mount on those two bolts and it just broke the case bosses out sideways.

I agree on the FROR mt. I fabbed one off thier centersection, very stout mount used with chained MM's didnt you say you still have 1 case mt. ok?

Erik, do you think I'll be fine with only one tcase mount?


the other side of the mount is fine ........ I'm guessing the side that broke got lose?? due to the front drive shaft its really hard to check those mounts on that side :(

Yes, the rear case and tcase mount are fine......

My problem is I'm about to build the floor and seat mounts and I want to fix this the right way NOW


I'm really thinking about getting the 4xInnovations mount for the rear case and see what happens ........




heres what I'm building........

I run a Front Range cross member, however I didn't like their skid plate, specifically how it mounted directly to the bottom of the tcases so I went ahead and put a Budbuilt skid plate under neath with 2 stock Toyota mounts and it has worked very well.

I ran one mount on the rear case for about three years and it worked fine. The only reason I put another on was I was at Marlins one day and he gave me a mount and hardware to mount it.

Um didn't realize the long term failure in your PM.

To me this seems like it could have been caused by motor movements, possibly some loose bolts. It was most likely a long term failure. Looking closely at the photo, and drawing an assumption, it looks like a lot of the cracked surface is fairly oxidized, meaning it's been growing over time. We have a lot of happy users running one of our mounts and on your current system it should be just fine. Adding the rear plate just seems like overkill and more stuff to get in the way in the long run. Strapping that motor down with some of our SD Engine mounts would be much cleaner, but admittedly not less expensive.

I would guess it was the OTHER side that was loose and the side that broke was tight...

I ran one mount for a while w/o problems too. My motor mounts were chained.

That's essentially what i'm doing... FROR plate on the back case, welded to a 1.5x.25wall DOM crossmember on urethane Blazer spring bushings, then a piece of 1/2" plate from the tube forward to the 2 stock tcase mounts.

I like the support of the FROR style mount, but I hated that their skidplate bolted straight to the tcases metal-to-metal.

I'm also running Trail-gear engine mounts. So yeah, I've got lots of vibrations.
