Thanks guys! I'll try all of the above... It would just be sooooo much easier if I had a freakin bench vice!
The grub screw is out. I just got tired of the wheel nuts backing off and began dabbing locktite on them.
FWIW, anyone who reads this post... I don't think you could ever find a more solid basher car than a Hyper 7... This car has been through hell and back, seen almost 10 gallons of mostly 30% fuel and the only parts I have had to replace were the chassis (I ramped the car over my extended cab S10 lengthwise, landed on pavement...) one front shock that went AWOL (when it landed on the pavement) and a rear gearbox from a couple years of abuse. I'm just now having to change the first wheel bearings, never maintained them, ran it through water, jacked them up. Water incident ruined my RZ-V01B, screw it, it was time... she paid her dues... And I've went through 2 flywheels, probably 10 sets of clutch bearings, one pair of shock towers (tried to hang the car from a tree). Has the original Ofna throttle servo (PCR RTR kit) original Hitec HS 645 MG servo that I upgraded when I bought the kit...
Car has been upgraded to quad brakes, extended chassis, with the longer universals, and added rear universals. And if they don't sell soon, I'll fit up a set of big bores...
Bang for the buck... Can't beat a Hyper 7! And... 3 models later, you can still find parts on FLEABAY!
