Default Slight wobble at 55 mph

I have noticed I have a slight wobble/shimmy at 55mph. I have replaced all the track bar bolts with 9/16x3in grade 8 bolts. Tires are balanced and everything looks great. Any ideas?

I got a wobble as well and checked everything you did. I think mine is due to either my camber being off (most likely slightly bent C's) or possibly the fact that I need to replace my ball joints as the passenger side are toast. Have you had an alignment doen recently to look at camber, toe, etc?

How many miles do you have on the ball joints. I only have 15k on mine.

Rotate your tires. If the wobble goes away or changes, it's tire balance. I've fought this battle a lot.

26K miles. Almost all of it has been with 35's and my wheeling is a lot of rock climbing so I am not exactly nice to my Jeep. My passenger side ball joints have about a 1/4" upward play in them. Driver side is solid as can be. I have a new set of aftermarket ones ready to go in. Just need to find the time and rent the tools to get the stock ones out!

Loose bolts in the suspension, bad ball joints, bad wheel bearings, a shot stabilizer, etc can let it wobble, but that stuff doesn't start the wobble. There hasta be a tire out of balance, or a tire out of round, or a tire with mis-aligned plies, or a bent wheel, or a bent axle, or some such to get the wobbling started in the first place.

I had same issue at 45-50 for awhile. I had my tires balanced not too long before it started, but turned out one was out of balance and causing my wobble. also the bigger the tire, the more easily and more often they seem to get off balance.

Had this as well but it just ended up being a tire with a small bubble on the interior (towards wheel well) sidewall. I looked two or three times but couldn't see it until I took the tire off. Felt relieved that this was the issue and not something more serious.
