My review of 4.88s on a 2nd gen with 34s

Another vote for 4.88's with 315's. I don't have much extra weight vs. stock and its made a huge improvement on driveability (mostly around town and <75mph freeway). MPGs slightly up vs. stock.

 

Drove up to Kentucky for a day trip Monday and averaged 13.5 over a light pass with just day trip type weight.. I shudder to think what I will be getting driving up to the continental divide around Wyoming and Montana in August fully loaded with boxes and RTT on top.

 

Any of you that went 4.88 notice any vibration noise or change in drive harmonics? When I hit 60ish on the freeway I getting a noise that wasn't there before the gear change.

 

The front end of mine makes some noise but it's because the backlash is just a little tight. I'm not worried about it, it'll wear in.
