The CV joints in the Ford Bronco's Independent Front Suspension (IFS) are easily vulnerable to damage by over-extension, in Broncos with suspension lifts. In other words, when your suspension flexes beyond the safe range intended by the Ford engineers, the CV joints can bind and damage the precision components of the joint, leading to anything from premature wear to catastrophic failure. Short of CV failure, over-extension can also cause tears to the rubber dust boot which is an equally labor-intensive repair (though less expensive) that can lead to more severe CV joint damage if not addressed.
We've had several CV joint and/or boot failures so we decided to address the issue once and for all by installing a diff drop. We chose the kit designed and sold by Broken Innovations, after following their thorough design process online. It's a very well thought out, complete kit that is available in several DIY options, from weld-it yourself to fully complete. You can learn more about it or purchase at [ Ссылка ] We swapped out the axles first, so if you're only interested in the Diff Drop install, skip ahead to 11:05 in the video.
While we were at it we decided to start fresh with a brand new set of CV Axles from Ford Performance (link: [ Ссылка ] ), since we had installed a pair of used axles when we swapped to the M210 FDU a few months back (see that video here: [ Ссылка ] ). The rusty old used axles were of unknown integrity but we had already torn a CV boot, so we thought it was prudent to just pair the new Diff Drop with a brand new set of axles.
As we've become accustomed to doing with our install videos, we've just gone ahead and included the entire process, including mis-steps and learned lessons, so you can learn right along with us. I'm not a professional mechanic and I don't present myself as an expert, or my install videos as definitive bibles on how to do something. We try to include it all in there because something we cut out might have been useful to someone. But I do speed it up when appropriate, and try to weed out most of the idle time in order to keep things moving. I hope you find the format useful.
If you're new to our channel, Steffie & Dusty bought Chanel as a 2-door Base model with no options except for the auxiliary switches. Over the past couple of years we've put it through its paces in stock form then started building it into a highly capable trail rig. Please check out our previous videos if you haven't seen them, and subscribe to stay tuned as we continue with the upgrades and off-road adventures!
