bump bump bump (almost a banging) at 25 mph(max noticable) mostly under accel. along with growl under accel. Noisy, more under accel 20 mph up. This is a used one I just bought has a new noise, the original had a whining growl under moderate accel from a start under a turn at times... Any help???

 

what axle? and how many miles?

 

what kind of axle, size, gear , ls or open , how old , how many miles ???

 

both are open 7.5". original is a 3.45(250k miles) and a broken spider shaft pin-bolt, can't inspect to see if it is messed up internal. The one I just bought is 3.73 ( w/banging ) is 96 (miles unknown) had a bit of metal powder in the magnet One of the brakes puked and locked one wheel.

 

pinion bearings. Mileage or bad job on the pinion seal can easily lead to this.

 

7.5 isnt the best axle to have. i recomend you upgrade to the 8.8

 

I am pretty sure 8.8 93-97 works on my 93. Any other years/vehicles that can bolt in, even if stance is a little wider or if I have to improvise a little.

 

i think any ranger 8.8 will work fine.

 

any 8.8 ranger axle will work, but make sure the gear is the same ratio, or the speedometer will be wrong,

 

3.73 vs. the original 3.45 will help with the taller tires. But,.. all the spring perches have the same ctr to ctr mounts??

 

i dont think the gears do than man, its the bigger tires

 

Gears do affect the speedo...

98-00 trucks are not affected by this change Previous and newer generation trucks are.
