i have a 93 4runner with a whining noise. i just bought this truck and i have a whining noise while under load. any speed. its an auto i put it in N and the whinging goes away. its only under a load any clues?

 

if its coming from the rear i suspect you got a bad rear end gear

 

Visit your local transmission shop.

 

gee thats really helpful

 

Check the fluid in the rear... replace it and see if that helps any. I have to agree with little runner.

 

could it be the alternator they can whine aspecialy under load

 

ok heres part 2 of this i do 65mph its whining throw it in N and the whining goes away

 

oops i forgot its a auto!

 

where is the noise coming from... in front or back?

 

it seems like front but i cant be sure im gonna change all the fuilds this week any suggestions on what i should use

 

If its up front it could be a few different things. I take it is a 3.0? Alt. could be a possibility but have you changed out the t-belt lately? Could the tensioner be causing the noise?

 

im still going with Alt

 

the t belt was at 101 it now has 200k however the whining doesnt change whing your reve the engine

 

this is why im stupified it doesnt change with the revs of the engine doesnt do it at any speed while coasting in N im stuck trying to locate this

 

when its under a load the gears in back are pushing against each other.when ya let off in releases that tension.if its not the rear end i'd be surprised

 

i guess thats the best place to start then! thanks any recommdations change fuild first or go right into changing gears?

 

start with the easy/cheap things first...




did you try getting rid of the passenger? they tend to whine quite a bit...

 

be sure & confirm thats where 1st.then just for giggles i would change the fluid & put in synthetic lube.if it has just started the noise it will go quite a while before you absolutely have to replace.when it is time you may be able to find a good used 3rd member & just change the unit out.or if you want to change ratio or add a locker this would be the time to do it.i just happed to have 2 3rd members used if they are the right gear

 

thanks everyone! im gonna start with the fuild change on AT tranfer and axles and go from there thanks so much for the imput
