    Nah, Ray Charles couldn't have seen this coming 'cause he's dead.

    Why can't Helen Keller drive?

    The Gen 2 boots are a completely different design. Porsche boots won't fit.

    Keep in mind the area it was tested. Out here in AZ, in a dry wash. Very dusty conditions.

    Heres thing I have tried so far:

    Armor All
    WD-40
    Marine Dry Lube (Teflon)
    Pam (not the girl....well...I tried her, but not on a CV)
    Marvel Mystery oil
    ATB ("Absolutly The Best"....no shit.....its the real name)

    Well, there is that ultimate FJ axle, but it's pricey as hell. Given that these Toyotas last forever, you may get your money out of them. as opposed to replacing half-shafts on a regular basis.

    Me, being the stubborn cuss I am, plan to give my lift (2.75 to 3 inches, depending on how the angles look) a shot without it. If the CVs shit, I'll have learned my lesson.

    Anyone running the DD runs the risk of the same damage. GAH!!


    FRONT diff lowered 1". puts it at more risk of impact.
    DD will transfer more energy to the front diff when hit.

    If anyone running these hits a rock at a slow speed, the same result can happen.

    Also, You said you were blowing CV's, then you lowered the front, and added the diff drop........Dont you think a bit of the reason things are kosher now is due to the lower front end??

    For awhile I was also the only case with a rollcage, only case with aftermarket seats and harnesses, only case with jounce shocks, only case with BudBuilt skids on a 2nd gen, only case with Giant Motorsports' LT setup, etc.

    In each case, I've provided advice and insight gained through the experience. I prefer to have my skids mounted as tight to the frame as possible, which is what I love about the BudBuilt skids. Yes, a looser-fitting set of skidplate would clear the differential drop by sacrificing clearance, but that wasn't a compromise I wanted to make.

    This time around, I'm providing photographic evidence that the drop kits do not lower the differential as much as people say they do.

    The damage I suffered was definitely due to the modified skidplates caving in, but they would not have needed to be modified had I not installed the kit that does virtually nothing for driveline angles.

    so wouldnt the true advice be to not modify your skids to run the DD if you chose to run it? :D

    :smack: :p

    Or run sloppy skids that don't fit tight to the frame.

    It's really the last photo in my first post that's the most important. Seeing how the differential is mounted at the rear of that arm shows that it really isn't lowered at all and is only rotated.

    What makes you think a skid that goes smoothly over the DD would not have the same result if hit? The energy of the impact is STILL transfered to the crossmember at that point. Mike impacted at a downward angle. The DD is going to magnify (via more leverage) the impact energy transfered to the crossmember.

    with that part of the skid giving way, it allowed the arm to take a direct hit from the rock. if a smooth skid was used that wasnt an all pooh (for obvious reasons), it would have deflected the hit and never come in contact w/ the arm like his did


    mike even said it himself....

    FUCKING BINGO!



    There is NOT a wall big enough that will sustain the force at which I want to smash me head agaist it with......




    ALOT of you guys are missing the fact that this drop increases the amount of force that can be applied to that area.

    You guys have fun with your diff drops and hold fast to the belief that it's doing anything other than rotating the differential.

    I can only facepalm so much this morning.

    The skid STILL would have given way. The impact was ahead of the diff drop. Energy would STILL be transfered to the diff drop, and the results would/may still be the same. Look at the fulcrum point. There is MUCH more leverage in which force can be applied to that front diff. thus causeing damage.

    the skid would have taken the blow and the skid would have never hit the arm where mikes did. no energy from the hit would have been exerted on the diff drop. in the edited post you quoted, mike even said that the skid would have deflected the blow if it were smooth. if a smooth skid can pass the blow w/o the DD, a smooth skid covering the DD that has space beterrn the skid and DD would also deflect it.

    Have you tried Dry graphite ? Maybe an aftermarket silicone cv boot ? Either way I have the DD and dont really have a choice as i'm at 3.25". 25k hard miles with my trd blower and my cv's are still perfect. Yes the DD should have a better design to it, maybe the spacers being connected by a bar for support for flex ? BUT it really does seem that the skid plate really made this situation occur. That weld box took the brunt impact and concentrated it directly into the dd spacer. That is the opposite purpose of the skid plate. Shouldnt the purpose of a skid plate be to spread out impact pressure across the whole plate & create less friction on the surface to help slide over obstacles ? Maybe the skid plate should be like a two step plate. One lower plate angled far enough to cover the dd points and than another welded on plate that lifts higher for more clearance ?
