As usual we had some issues, but let us reiterate: this is a prototype for a YJ. John has sold numerous axles for TJs and hasn't gotten a single complaint. Also, every issue we encountered has been fixed by Solid.
First, the shipper dropped the crate and broke it, but there was only cosmetic damage to the axle. Not Solids fault, but be aware this thing has some heft to it. Be prepared and if yours is dropped, get a claim number BEFORE the shipper leaves. Just in case.
Second, we had a couple of minor issues with the hard lines for the brakes. The standoffs for the brake connections at the wheel end need to be about 1/2 inch longer to ease the transitions around the u-bolts.
The axle could also use a few blind tapped holes in the axle tubes to allow for brake line hold downs. John agreed and is making this change for both the YJ and TJ versions.
The last brake line issue was routing the new lines so they didn?t look like we were drunk when we bent them. We recommended a pre-bent set of lines, but John told us that every time he's tried this as a production idea he gets more folks complaining that "it's not where I need them because (insert unique Jeep issue here)." We can understand that, so you'll more than likely have to bend your own hard lines to fit your Jeep.
Third, our diff cover has a 9/16 allen stock fill plug. This requires you to carry/buy yet another tool that has a single purpose. We recommended going to a 1/2? or 3/8" square drive so you could just use the ratchet you already have in your tool bag. They're on it and sourcing new fill plugs.
