    Caster still off after Alignment. Is this normal?

    Mine was vibrating and an alignment fixed it, toe was out a fair bit. I put in new upper ball joints recently and had to take it on a road trip before i could get an alignment and a vibration developed. Inside tire wear occured and after the alignment the vibration is almost gone, few more miles...

    Caster still off after Alignment. Is this normal?

    It's your truck. If it's vibrating because your alignment is out then I'd gladly spend the $100. I've been driving one of these lifted with the t bars cranked for years now. $100 is better than a vibrator. Unless your into that sort of thing

    ECM issue

    Order a ECM from one of the tuner sites that does L5P tuning and take it to the dealer. Either that or sit with a broken truck until they are off backorder.

    Injection/Pilot injection rattle

    I logged converter slip it isn't that. Clutch stays locked. It's a Limitless 1078 with very minimal miles on it and no abuse. I can go wide open throttle on any tune and it locks and no slip. This issue is under very light throttle with little load on the engine. Mark said some LMMs have this...

    Yes it has to be timing. Only looking to modify where it happens. This doesn't have a sound to it, just feels makes the engine jump rpms +-30/50 rpm. Mark says it pilot injection rattle and he calmed it down so I believe him.
