JKS trackbar bolt snapped


Recommended Posts

Just an FYI for those considering a JKS trackbar, my JKS trackbar bolt disappeared, so I am assuming it boke off. It looked to be from the kit a nickel based bolt, so I replaced with an 8.8 high tensile steel bolt.

 

I am not trying to say bad things about JKS, but I just want folks to be aware of what happened to me. I was very lucky, I was just on the freeway, and when I exited I noticed that my steering was sloppy. I pulled up to my house looked under the truck and discovered the bolt was missing! I had torqued it to spec when it was installed, anybody have any advice on a bolt replacement? I didn't want to put lock tite on a bolt that should easily bolt off, any comments or suggestions? :cheers:

Dayem, you were lucky. The axle end Joe? I just reused the original bolt w. locktite when I put my Teraflex track bar in, because you don't have to take one end off to adjust it. Or did you have to drill out the holes w. the JKS bar?

Yours came with a bolt? :eek: :brows: lol I've had mine for quite some time on my Cherokee but it didn't come with a bolt. It reused the original bolt which was too "skinny". There was a lot of slop between the bolt and the track-bar end. I had to visit the local hardware store and scrounge through bins of bolts with a digital caliper to find one that fitted correctly.

Don,

Yes on the axle end, I drilled out the original hole and after reading an old thread (I think you commented) that it could weaken the housing (I like your trackbar better). I just bought the trackbar back in February and the bar came with a nickel looking bolt.

 

jpnjim I am thankfull to be alive and that rollover video is brutal.

 

I will never again assume that just because something like a bolt comes with a kit that it must be OK, its grade 8 for me or a trip to the hardware store.

Technically, the factory bolt is metric, so "Grade 8" would not apply. Much of the problem arises because many of the aftermarket manufacturers don't take the trouble to make their parts in metric sizes to match the application. So you either use a bolt that's too small for the hole in the track bar (leading to slop), or you drill out the hole in the frame -- thereby making it forever impossible to revert to a correctly-sized, metric part.

 

Many of the control arms offered on the aftermarket have the same problem, as did the Trailmaster brackets that were on my '88 MJ when I bought it.

FWIW, On my TJ the frame side is a fancy pants long bolt with zerk and I had that one snap. Basically I had it adjusted too short and it was hitting my pumpkin while wheeling and that added stress, which was my fault, caused it to break. I called JKS told them how big of a bone head I was and they sent me a new one free of charge. I personally am I huge fan of their products and customer support.

Did you read my post? The OP said he used an 8.8 grade bolt as a replacement. I suggested he use a 10.9 which is the metric equivalent to a grade 8, not 8.8.

Metric or standard I think I goofed as I didn't use locktite to tighten her up and the nut came loose, if so my bad and either way it could have cost me my life. I hope others will take a trackbar installation more serious than I did. :cheers:

I don't buy any aftermarket part, especially concerning suspension, steering, and/or brakes, that requires drilling into and enlarging the stock mounting points, unless of course rot has destroyed the original mount and you have no choice. If you do, you usually eliminate an essential point of return w/o a whole lot of work I really don't want to do. :cheers: And yes, Locktite, while not a complete guarantee the fastening will ever loosen and fail, does help to put the odds in your favor. :smart:

Sometimes there is no choice.

 

When I bought my '88 MJ it had a 4" Trailmaster lift and a stock track bar. The axle end had been reloxated to a new hole that was uncomfortably close to the edge of the bracket. The stock bar was shot anyway, so I bought an adjustable and mounted it in the stock location. But ... the hole at the stock location had been badly worn into an oval shape, and there was no way the track bar was going to stay in one place.

 

Auto tech buddies to the rescue. One of my friends from NAXJA is a VW shop foreman. Apparently around that time VW had some kind of recall or tech bulletin operation that came with a parts kit including some high-grade metric bolts and VERY thick, hardened washers of the same diameter as the track bar bolt (10mm?). And not all the parts got used in every operation, so my friend had a box full of these bolts and heavy washers. So I took the truck to his place one day and he welded one of the washers into the axle bracket over the original hole. Better than new.

 

But it should have have been necessary. The previous owner was a teenager who must have pounded it through the woods with the track bar bolt loose.
