Re: What did you do to your truck today.The 3rd chapter
Just picked up mine from Custom Differentials in Bloomsdale, MO. Jeremy's team upgraded my 12-bolt open diff 3.08 to a 3.42 posi. No more whine and now 2-wheel peel! The old pinion bearing was heading south in a hurry. I can now hear myself think while cruising down the interstate. I also needed new axles. Tomorrow I'll pull the speedo cable on the 700R4 and see what driven gear is in there since my speedo is fast by about 15%. Per the rule, add 1 tooth for every 5% difference if the speedo is faster than actual. Thanks Jeremy!
