ok, so i THOUGHT i was going to replace the rear brake backing plates, which, thanks to the 428.7 metric tons of salt michigan spreads all over the roads every winter, have rusted completely in half. i knew i would have to open the rear axle cover, to remove the c clips that hold in the axles. not a big deal, i have done it a number of times. ON OPEN REAR AXLES. this has some kind of traction control or posi-traction device sitting right in the middle of where i need to go to remove the c clips. i spun the axle 180 degrees, and i can see to access the clips. but i am not sure if there is enough room to do so, and i am really not not sure if or how many pieces parts / shims / springs, etc. will fall / fly out @ 1,247 MPH if i try to remove the shaft that the spyder gears ride on. i have been into several rear axles, mostly old school Mopar hot rod stuff. i have set up 4 (3 mopar and 1 ford 9 inch) gears, and gone thru old school posi units. but this is much newer than anything i ever did. plus those were 30 years ago (man, does time fly). is there anyone out there that has been in one of these? that can shed a little light on my dilemma? am i opening up a huge spring loaded can of worms here, or is this something a decent home mechanic can handle?
