Broken Stock Mounts

[pdw]

I have noticed that the shock mounts on the front axle of my YJ are only welded on the outside of the brackets.
You might have some better luck if you run a bead along the inside of each bracket....

Also, I noticed that my lower shock mounts were both a little bit tweaked by the rocks. So, after straitening them with a large crescent wrench I welded a 3-4" long piece of 1/8" angle iron to each side of the mounts. This give the entire mount more stability without having to add a bunch of weight.
Just a thought....

One of the first things I did when I put the lift on was truss the CA brackets, the Drag link brackets, and the POS UCA mount on the PS of the Dana 30 Front. What a weak-assed POS that thing is. Haven't broken any of those mounts since one on Holcomb two years ago, but then again I only do the bunny trails... And Do what Blain suggests, weld the skids on your LCAs to the axle tube for more support.

Curtis,

Due to some mud build-up I can't take a quick photo, but my mechanic welded a pair of triangle shaped gussets on each side of the mounting tab. My original tore loose and now is very well braced and rigid.

mrblaine What is a good way to brace the trackbar mount?

Now what you need to watch for is your trackbar mount ripping out of the frame. If you beef up the steering box mount and brace it, the next thing in line that takes the abuse is that mount. I've welded several of them back in on trail.

Ha! Well, I can say that I have learned otherwise. Just for the record, I have been regularly offroading in Mr. Green for just about three years. In early January this year, I had a rear shock mount shear the welds after running Isham Canyon:

Had you not increased the leverage against the stock welds with those shock extenders, they would in all likelihood still be fine. It's not the mount's fault you exceeded it's design parameters.

After running Hairy Crack on the last day of January, found that I had a cracked and crushed lower control arm mount on the driver's side. Notice the mis-shaped mount in this pic:


I straightened and re-welded the bent and cracked parts, and added extra welds to both of the front lower control arm mounts. I then added a 3/16" sheet metal plate to keep the mounts in position:

It's hard to tell from the pics, but did you run a weld across the front where they touch the axle tube? If not, you should.

Okay...so now I'm becoming a believer in this stock mount problem. The real kicker (and a break that I haven't heard about before) is that after the Martinez Canyon trail in Arizona, I heard a popping noise coming from the steering, especially when I turned the tires to the passenger side. I ran Bullfrog trail last weekend and it got worse. After some assistance from my wife, I found the problem. The bracket that the steering gear is bolted to was shearing from the frame! Check out these pics, judging by the rust, this has been a problem getting worse for a while:


So tonight, I pulled the steering gear and re-attached the mounting bracket with a pretty heavy-duty weld. In the process, I found that one of the mounting bolt holes was also cracked:

After fully re-welding (using a heavy-duty weld) all four of the contact points for the bracket, I finally felt comfortable putting everthing back together:


So, a long story to get to this point... check your suspension mounts after every adventure! It's more important than you may think.

I will from now on. Just my opinion...

the 97-99 frames and brackets are not welded as well as the 2000+ brackets.

Same with the middle spring hangers on a CJ(not sure about YJ). Their rivited to the frame. I welded mine on along time ago. You CJ guys should check those. Welding mine really tightened up my steering.

Mike the control arms with bushings instead of Johnny joints or heim joints put a lot of stress on the control arm mounts when flexing since they bind.
If your control arms are fitted with heim or johnny joints on both ends that should not be your problem, rubber bushings on one end is not bad either

Hey Mike! Have you considered one of the steering box braces for guys like M.O.R.E.?

Yes, I installed one when I blew up my gear box on Shedder a while back. I didn't think that it was doing much until now. It has pretty much been what was holding the steering gear in place!

Hey Chris (Elusive), I have the adjustable upper & lower control arms and I assume that they are adjusted correctly since I had an experienced guy install the lift kit. Is there a way to check?

[Elusive]

the 97-99 frames and brackets are not welded as well as the 2000+ brackets.
I tore almost all the brackets off my 97 frame (including the steering box just like yours), but my 2000 frame has only lost 1 UCA bracket.
I also think that the control arm design helps keep the brackets alive. The adjustable uppers and lowers with RE joints have helped prevent binding on the arms.

[COLOR="Sienna"]Going to check the YJ today! I know I have some issues with my tranny skid plate mounts already...this will just add fuel to the welding fire I suppose.[/COLOR]

I tore the stock front shackle mount off the frame on Rattlesnake and ripped the bottom rear shock mounts on Hairy Crack. I replaced both with Currie chromolly mounts and mounted the rear shock brackets level with axle instead of hanging straight down (also raised the top mount by the same amount). An overhead lift really lets you clearly see whats happening down there. I noticed from the Bullfrog pic's that Chuck had Kurt check his stuff out as he drove by (OVER!)him. Haaa....

Hey Mike! Have you considered one of the steering box braces for guys like M.O.R.E.?

Reinforce the power steering gear box to the frame with this heavy-duty brace. If you have tires larger then stock, this brace is a much needed item. It is the best insurance you can install on your Jeep® to keep the box from being "torn" off the frame. The brace is powder coated and the clamp is zinc plated gold. All mounting hardware included, simple bolt-on design. No drilling or mods required (for most applications).

Last Saturday you saw how I like wheel. I have used one of these braces for a few years now, and I have had zero problems.


P.S. I recently plated the outer portion of the frame that the power steering box mounts to with 3/16" steel in order to reduce the opportunity for flex and stress. Right there!

Totally agree!! Guys.

I check as soon as I get back or the very next morning. Weld seams are usually overlooked; but too important to miss!
Mike, those are some fine PICS for examples to show...thanks for sharing.

Excelent advise, it is something that should be done every offroad trip, especially on rocks. Those Jeeps take quite the beating. I still need to do some fixing from the the abuse of the hairy crack run
