Holy Trackbar Bracket

Previous owner installed a RC 3.25" lift and RC track bar in the front.
He had it installed by a shop and looks like they drilled another hole to the lower right of the original hole. I am planning on putting a stock bar back on.
Should I worry too much about the extra hole causing stress on the bracket? The metal is thinking around the mounting point now so I could see it possibly causing problems.

Some say yes, and some say no. I drilled a hole to remount my trac bar. No problems for me, that was 148k ago.


If you're worried about it read this. http://www.jeepforum.com/forum/f9/br...racket-905624/

I didn't re-drill (and I'm a cheap ***) on the one fact that if there is one component that you don't want problems with on the road, it's the track bar.

Doesn't seem to be effecting much at the moment. No problems so far just wondering. I'll have to see about it.

I would replace the stock bolt with a stronger metric bolt and crank down on it. Keep it tight, and you shouldn't have any problems. http://www.jeepforum.com/forum/f9/un...ml#post7330152

I drilled the hole and about 40k miles later it wallowed out and gave me some wobble. JKS adjustable track bar is fairly jeep and easy. That's what I did. I have that same lift.
OP are you level with that lift? Bc from day one my front sags like crazy.

That's because you didn't tighten the bolt down enough so there wasn't a sufficient clamping force to keep the track bar from moving around. Using a stronger bolt with more than the required 55ft lbs will keep that track bar in place. Or any track bar for that matter.

Oooo yes I did. it was in a bind when I first did it and went the bind broke loose down a mile road I had some death wobble. I put a 2 foot breaker bar on it and went to town. When I drilled the hole I have to move the drill around a bit to get the right hole diameter. That's likely what caused it. I also just feel like that new hole is just too close to the edge it's better to just get a new trackbar. JKS has something similar to a Johnny Joint on the frame end and that's better in the long run than the stock stuff. JKS is amazon prime as well for us college kids with free prime

I can't give you an accurate answer on the lift. Previous owner installed it and from what I've been told its 2 years old. It's sagging all around and I can't stand it. Replacing it with a 3" BDS lift.

I ran my first axle on a redrilled hole no problem. This axle came with a redrilled hole but I suspect it must have been in the early stages of wallow because it is extremely wallowed now. I crank down on it from time to time but it always loosens up eventually. I plan to repair it very soon. This axle doesn't have much longer of a lifespan under my rig anyways.

I replaced the stock bolt which for me did keep working loose for some reason. I used a metric 12.9 fine thread bolt with a lock washer and lock nut. Hasn't worked loose since. May want to give that a try.

the stock M10 bolt can only take about 45 ft-lbs. if you put a 2 foot breaker bar on it and went to town, you stretched & yielded the bolt...and it will not hold clamping forcing.

people do that all the time because they don't understand there is such thing as too much torque on this bolt.

Here's two things you need to read:

http://www.jeepforum.com/forum/f9/br...racket-905624/

If you're going to do the redrilled hole thing (or even if you're not), use the Class 12.9 bolt and weld the reinforcement plate on the stock bracket. You won't have problems.

yea I may have. That was back when I didn't know what I was doing. I use a digital torque wrench now and upgrade my hardware to grade 8's when I'm looking for something to do on a Saturday morning.

the Class 12.9 bolt mentioned previously is stronger than grade 8 and can take more torque.

O yea sorry I just reread that. Mostly bolts I have swapped have been stuff that doesn't take a tremendous amount of load but I will definitely look into 12.9

grade 8's should be able to tolerate the amounts of torque needed to properly tighten to 70%-90% of their proof strength. 70% for bolts that may need to be removed often and 90% for permanent ones. That being said "overkill" is the name of the game
