Ah but does anyone know why the right rear spins when you stomp the gas?


Well if you go to newtons laws of phsyics, the one about every action has an equal and opposite reaction applies. The engine torques toward the passenger side of the car. That torque reacts in the rear end and lifts the passenger side tire causing a loss of traction, because it is lighter than the driverside tire which is being forced into the ground harder.

To counteract that effect you can also preload the passenger side rear with an airbag or other device such as a weight jack. no it isnt a locking differential, but it does work to a degree. In a low traction situation, such as ice, mud, or snow the tire with the least traction will spin first. Whereas a locking diff will put torque to both wheels evenly so to limit slippage.

unless your engine rotates the other way, you will always lift the passenger side rear. Provided the driver is on the left hand side of the car.

So then... what tire spins first in a front drive application? (sorta trick question)

 

thanks for the explination guys! ::rubs head:: uh who cares, FWD SUCKS!

 

Emp its supposed to make you think about it and come to a logical conclusion, or to find the answer in automotive literature therefore expanding your knowledge base for further reference. That way people wont make stupid mistakes posting bad info..lol.. Not that you have, its just better to have good info and share it than bad info and share it..


iIts public service and an education I paid for (either school or blood and sweat equity/costly mistakes) dispensed to you for the cost of the internet access...

 

How about just calling a limited slip differential an LSD?
Just don't tell a cop you have an LSD in your rear or you'll be subject to a strip search.

 

k gimmie a sec to think about fwd

well lets see, the engine weight is in the front on an FWD car puttin the weight pretty evenly on both front tires, however the motor is kinda sideways (i think with i4 cars and stuff) so...both wheels pretty evenly? for some reason i wanna say the front left but i say both evenly, final answer. (enlighten me)

but now that i think about it, the driver is on the left side so the right wheel spins.

 

It depends on the orientation of the engine in the chassis and where the axles are. An Olds Toronado had the engine installed the normal front to back way for years, and they were all front drive. So in that case, the right front lifts. If the axle is infront of the engine as it is in some 4 cylinder cars the left one will lift. Some engines are in backwards from domestic front drivers, but if the axle is rear of the engine, the right front lifts.

 

I'm assuming you have an 8 inch rear although you never made that clear. These guys aren't the cheapest place for these parts I'm sure but they have great parts and know their stuff.

chillin something about aht pic just does it for me... Maybe its just wishin my fastback had paint on it...

more pics of the rottisserie?

 

yea i really dont know much about it thats why i made this post. i wanted to get some information on it the names the diffrences and stuff like that.. how do you tell?

 

holley finally got back to me, they said 3.55-3.70 gears are what i need. thanks to this thread, i got a few places to look for a complete differential, or i will buy the ring gears and pinions from summit and a posi spool, i havnt looked for them at summit yet.
