just curious......

1. what is the difference between a shock and a strut?


2. what is the difference between 4WD and AWD?

4wd can be switched from 2wd to 4wd
AWD cant switched

no, there is also full time 4WD

I think the REAL difference is the amount of torque transfer, which is 50/50 in 4WD, and it's 60/40 in AWD. I dunno what the real and actual technological difference is though.

A shock and strut are both types of dampeners. A strut turns with the steering, like a MacPhearson, whereas a shock doesn't. Some would also like to differentiate them by a strut having the spring wrapped around the dampener, in which case that would make our front dampeners also struts. A shock by this definition would be external to the spring, like on the back of Toyotas and VWs.

i thought like 4wd is all the time... ie impreza...

while the awd would have for instance the rear wheels having power all hte time and when the rear tires slips the fronts get power to stabalize it??

i remember that from seeing the dodge stealths cause they advertise AWD on the side of them....

a shock is just a shock.. a strut is a shock with a mounding base for a spring to sit in...more of an assembly.. honda uses struts..

a plain shock would be more in a truck application to give damper assistance to a suspension setup.. im pretty sure a straight shock will neve have a spring wound around it...


I guess the easiest way to put it is just a dampner and a strut is more of a suspension peice..(note a strut has a shock built into it)

I may have confused you lol

somone should post pics, its the easiest way to explain it..im to lazy lol

I think the difference between the 2 is mainly a name .....

but more importantly Punk if you reverse your names and difinitions then you'll have it..

an impreza is AWD all 4 wheels go all the time... power is transfered from any wheel thats slipping top one thats gripping to keep the power being layed down

a CRV is 4wd.... the front 2 wheels do the driving and when they slip the computer will engage the rear wheels and send some (10% of the power back to them).

gatherer is a bad *** bitch heh

bah switch them then i'm right.... which is usually the case.... i work a mindless job so it takes an hour or so to wake up again from it

ok awd the transfer case is alway's ingauged where 4wd you can engage adn disengage the tranfer case..there is the technical reason between them....

well thanx for that info, i was just curious, i knew there was a difference between shocks and struts, but i thought that AWD and 4WD were 2 different names for the same thing

boy that was helpful

Differences between awd and 4wd



awd generally uses a transverse mounted engine with a transaxle. Attached to this transaxle is a transfer case, then a driveshaft, then a rear differential. Awd is on all the time and traction controll is generally integrated with the system. For instance Audi uses a set of viscous couplings to sense when the wheels are slipping so it can apply power to a wheel that has traction.



4wd gernally uses a conventional rear wheel drive transmission and also has a front differential seperate from the transmission.


There ya go!

^^untrue wrx's are setup as a rear driver...where as dsm's are setup as front drivers, good point but not always true

awd's you have to flat bed are you will burn teh rear dif and vicious cupling (sp)

Ah , i stand corrected, but i was speaking generally, good pionts tho
