One of the most problematic features on Jeeps and Broncos are the anti-sway bar disconnects. I put aftermarket manual disconnects on my Bronco but took them off after a short period as I noticed they were wearing unevenly. I have to think the Ineos folks were thinking of reliability over rock crawling.
Yeah - the electronic disconnect in the Jeep and Ram is known to experience failure if the electric motor gets submerged in water. They need to fix that for sure. I'm not familiar with the one in the Bronco.
Most people have a much better experience with manual disconnects. There are four that I know of, and probably a couple I've never heard of:
Currie AntiRock ($600-$1400 depending on options)
ORO SwayLOC (~$800)
Evo No Limits Manual Sway Bar Disconnect ($112)
Terraflex Quick Disconnects ($174)
I have a few questions - if you don't mind:
1 - Which manual sway bar disconnect did you install?
2 - How long was it before you noticed uneven wear?
3 - What part wore unevenly?
4 - Could you have replaced the worn part or would you need to replace the whole kit?
Often, performance parts need more frequent maintenance than stock parts, or might need more frequent replacement. Its that old idiom "you have to pay to play". So it might come down to how long the parts lasted, and was it worth it to you to have a disconnecting sway bar. If the answer is "yes" the performance was worth the cost (in terms of $ and time), then you just replace the worn parts every X number of years, and think of it like an oil change.
Another analogy that might seem more relevant than on oil change: I've got a performance suspension on my truck. It is awesome. It performs way better than stock both on road and off road. However, sometimes it squeaks - and that is really annoying - and I've had to rebuild two shocks, and replace two joints on the upper control arms (54,000 miles on the truck). I would not have had to do any of that work if I had kept the stock suspension. Has it been worth it to me? Absolutely yes - both in terms of the cost of the suspension, and the cost and time involved in maintenance.
