Well this is a fun story. When I bought my '06 SS S/C the rear subframe was tweaked out of spec making the driver's rear tire stick out a little. It created an annoying amount of road noise and obviously was contributing to extra wear on both the tire and hub & bearing. Well dealer paid for that to be replaced with another subframe from an '06 rather than new, grr to that but I'll accept it. Now she's in spec and all nice. Is the rear subframe setup unique? There's no axle back there, just a pair of hub & bearings for the wheel bolted onto the subframe. I've never seen that before.


Also, which of the two front wheels is the drive wheel?

 

BOTH of the wheels are driven, thats why there is an axle going to both.

 

unless you have G85, the one with traction is technically driving the car. With 100% traction they are both pulling your car lol. was that really a question? lol

 

I don't actually have the G85 option so I'm trying to find out which of the two wheels in the front will actually be pulling the car.

 

heres ur answer

 

One front wheel drive cars, just like rear wheel without posse traction, doesn't only one actual wheel receive direct power from the engine?

 

nope, they equally get power, until one looses traction. i dont get why people think only one wheel will spin.

I was pulling my friend out of a frozen over ditch once in my old jeep. I had it in drive and got out when it was on the ice. all 4 wheels were spinning equally, because they all had 0 traction. Same principle

 

Nope. Power is delivered to both wheels unless one looses traction - posi will shift power to the wheel with traction, open diff will shift power to the wheel without traction

 

aww man u were soooo close. all true except it doesn't shift power, it locks both axles together

unless ur using traction control, and that would apply the brakes to the spinning wheel and then i guess you could say it shifts power

 

Picky picky But true, caught with my brains down...need another coffee

Oh, and to the op - what you are calling the "rear subframe" is actually the rear axle assembly, it's a twist beam design. Quite common on lower end fwd's - like every mopar mini van on the road. Cheap to build, lightweight, relatively strong - but not near as nice as a fully independant setup.

 

dude that made me lol. i've never heard that one b4

 

I call it the subframe because that's basically how it was described to me and I said earlier, I've just never seen it before. I'm no mechanic so I wouldn't have seen any of those.

 

An open differential WILL drive both wheels with EQUAL POWER as long as one doesn't have a significant traction disadvantage. If you're pulling with one wheel, you have a serious problem.
