Urgent Question about mounting a rear tire carrier

I was hoping to get this thing done this weekend but I keep getting hung up.

Right now I'm using 4"/1" C-Channel in a configuration like the below.

I drilled the C-Channel and bolted it to the rear-crossmember.
How is that going to work? The bumper and tire-carrier are only 1/8" thick, and the C-Channel is 3/16.

Will this hold everything on?
Is the cross member strong enough.
It's all in good shape (no rust)
and I can't do any of that tie into frame stuff, my YJ has shackles in the way.

Will 8 bolts through the c-channel into the cross member do the trick?
I'd really hate to have to take the bits of C-Channel of.. they were a real pig to get on.

Re: Urgent Question about mounting a rear tire carrier

hoe much does the entire thing weight? (tire wheel carrier and bumper)??
If it is a good strong clean weld then I think it should hold. It probably wont give you any problems untill you bash it into a rock.

Give it a try, and if you cant tie it to the frame then what else can you do?

Re: Urgent Question about mounting a rear tire carrier

the welds should be strong..

I'll do them properly not just fire up the welder and start making sparks..

I've added some mondo (read: large) washers on the inside to protec the crossmember from allowing the bolts to pull through..
If it ever needs to come off it's going to be a job for the grinder as I can't get the bolts out..

the welds will be 12" long, top and bottom, either side, thats a total of 48" of welds.. 1/2 in tension, 1/2 in compression. the inside welds will only go in 2-3" as that's all I'll be able to reach..
never the less that will add another 24+ inches of weld area.

Re: Urgent Question about mounting a rear tire carrier

I just built a rear bumper, but in addition to bolting it to the rear cross member, I made some brackets that go THROUGH (bolts) the crossmember and to the frame. They are 3/16" t-1, extra strength for the 2" reciever hitch I have on the bumper.

Re: Urgent Question about mounting a rear tire carrier

Pilot.. I saw something simmilar on jeepfabrication.com

BUT.. When I look at mine I have a shackle mount right where they say to bolt the bracket to the frame..
I'm wondering if they are on a TJ or something..

your talking about a CJ5 right? Meh..
I've got the washers on there and I'm confident it wont pull out of the cross member..

On one hand I'd ask you guys to imagine you were driving behind me.. what would you want.

On the other hand, I'd ask you guys to imagine that were supposed to go out for a beer tonight, you going to wait at the bar for 6-8 hours for the extra bracket, and then buy me a beer instead of me buying you a beer cause the project ran over?

It's all a big gamble.
and I don't have to drive behind my own Jeep.

Worst case scenario is tha it sags, I notice it and cut it off and start again.

Re: Urgent Question about mounting a rear tire carrier

[img]images/icons/tongue.gif[/img] Dear Kat guy: When we faced this very same dilema with our CJ, we had a rust problem in addition to the shackle considerations. What we did was make new spring hangars out of heavy square tube with a bushing inside so THAT was then our new spring perch and we welded those tubes and some side plates to the frame to restore the strength, and then our actual bumper bolted to THOSE pieces as well as the cross member.[img]images/icons/smile.gif[/img]

Re: Urgent Question about mounting a rear tire carrier

Hey T

I`ve got the same scene as you and nothing has fallen off yet .
You know what I`ve noticed dude , there are practically NO YJ`s or CJ`s around here sporting a spare . No ones running one . I think it`s a cult or something . I keep a big bottle of that emergency inflate in the Jeep at all times . When I take it out of town , I`ll toss on the spare . Til then I`m with the rest of em`

Re: Urgent Question about mounting a rear tire carrier

Infernozx:

I've hit jeepfabrication exactly once, but plan to hit it again. Since I don't own a welder or torch, I use my father's equipment (probably why I don't own one--I can borrow any time!) The down size to this is that he likes to kabitz my jobs....and since I currently have my jeep parked at his house (I own a duplex, but my garage is all woodshop--he comes to my place to woodwork, I go to his to work on my rigs) he will sometimes go out and do something I mentioned to him I would be doing--but doing it HIS way! (when I'm not there so he can just present me with a fait accompli) The brackets were his idea, but I agree with them. If I'm really stuck and I've got some ham-handed inDUHvidual in a fullsize giving me a hand out, I don't want him jerking my reciver, bumper and rear crossmember out of my five. Also, I tend to build extra heavy. Comes from when I used to work on Cats and stuff.
