if you have a RWD car and put the hole axle upside down will it drive slow?

Question

like its in reverse and make a sound like reverse

Answer 1

Upside down ,backwards or inside out -the ring and pinion gear ratio remains the same - but on the noise part the reason most manual transmissions make a different sound is the REVERSE GEARS ARE STRAIGHT CUT and straight cut gears WHINE its that simple -I don't know where some of these answers come from-lol but you are right about some cars making a noise in reverse- in the muscle car era the muncie "M-22 ROCK CRUSHER" transmission had ALL STRAIGHT CUT GEARS and it was tough but the noise was loud but the other hot rodders envyed you!

Answer 2

the reason cars make a different noise in reverse is because they are usually driven forward so all the gears inside of the trans become worn in a certain direction so when you are in reverse you are driving the gear train against its normal direction of operation which is against the direction of the normal wear on all the moving parts if you did turn the axle upside down it would make a noise for a while until the diff unit run itself back in but in theory would run at the same speed any mechanical device that is run in one direction will be noisier when run against its usual operating direction have you ever used a metal turning lathe in reverse ? the make hell of a noise as do hydraulic drive hubs when you reverse the the oil flow to drive back wards I have for the last 20years been building road paving machines that only usually drive forward but sometimes you have to reverse the machine onto a trailer to transport the thing between sites if the machine is an old model when you reverse it at any speed the drive hubs scream like a banshee as the are going in a unusual direction a bit like a car in reverse gear only a lot louder

Answer 3

it would droive the same because the entire axle being in upside down is the same thing as having it flipped end over end,

its jut that the pinion bearings wont get oiled properly because the pinion gear is usually located lower than the centerline of the axle housing and plus it would be impossible to mount an axle upside down in a vehicle because the mounting hardware would not be able to be used


im not sure why this question was asked but its sure amusing

i am curious of what vehicle you are in RE of and what kind of noise do you hear and when ?

growling, grinding, scraping, howling ?
coasting ?
under load ?
slow speed ?
higher speed ?

only in forward ?
only in reverse ?
in all gears or only one ?
come or go when brakes are applied or released ?


good luck

Answer 4

It will still move at the same speed. The sound you hear in reverse is coming from the transmission.

Answer 5

no. you're thinking too hard. it's a simple system that gives the same ratio any way you turn it.
