    I am installing disc brakes on my 66 CJ5. Does the position on the caliper look correct?

    If I try to turn the knuckle to a hard right turn the caliper makes contact with a bracket of sorts welded to the axle tube. Is this bracket needed? What is its purpose? The driver side doesn't have it.

    You need to show the other side so we can see where the bleeder valve is located. It needs to be the high point.

    I don't think that is stock. It looks like an extended spring perch for an over axle lift. Did you change the springs on the Jeep and return it to spring under?

    No, it was always spring under. And it's only on the passenger side.

    that's a D27 for the V6. Its got a stop so that the axle doesn't crash into the engine if i recall correctly. cut it off but be aware of where your axle will smash into whatever is above it like the oil filter

    Is there a matching bracket on the frame that a bumper would contact? Depending on the year, Jeep used an extra bracket on the axle (or between the spring and the frame) that changes the axle direction as the springs compress. This apparently prevents the drive shaft from hitting the starter on hard, full compression. A view straight on from the side of the Jeep would probably help.

    Looks good bleeders is up

    That's just a bonus feature on the D27 25's don't have that. It is a torque arm that should have a bump stop to limit drive shaft to starter interference.

    Well shucks. I replaced the frame with an M38A1 frame. No more bump stop.I think that bracket is going bye bye. Thanks everybody for your input on my forever build. :)

    That's the anti-torque arm for a V6 Jeep. There should be a bumper that it pushes against on the frame if the axle wraps much. If the frame bumper is long gone and you don't have any issued with toque wrap, you can just cut it off. The 4-cyl jeeps don't have these.

    To add more info, I think the original intent was to prevent the front driveshaft from hitting the starter because the clearances were very tight. If you have a lift, it's probably not an issue.
