ok heres the deal the rear end on my 90 formy wines at certain speeds but not other.... like if im goin 50-53 i howls an whines if i bump it up to like 6 it is completely silent????wtf

i figured it was the gears im not really sure if it stillt he stock 3.23's because my speedo is a little slow and as you speed up it gradually gets worse....



any input?
thanks

 

sounds to me like someone put a 3.42 or 3.73 in it, or to that whereabouts, and didn't have the backlash adjusted just right, although that should wine louder as you go faster, but that's about the only thing I can think of...

 

if the backlash is off do i need to pull these gears as soon as i can or will it be okay if i jus5t leave it alone??

 

Well, depends on how long the problem has been there? if it's been a long time, then the damage is probably already done, and the only worse it will get is shearing the gears, or the head off the pinion. if it just started, then the longer u drive with it like that the longer it will wear an uncorrect wear pattern into the gears, and make them weaker/more suceptible to damage. Different manufactures state different ammts of acceptible backlast, i've heard 2-6 thousands, and 4-10 thousands. But if it's been doing it for a while, and gets worse, plan on getting a new ring and pinion kinda soon, if it just started, see if someone can pull u'r cover and check the backlast on it with a dial caliper and see if it has caused damage and can still be adjusted.

 

hey thanks man ill have to see what i can get done..
