| | | | Joined: Sep 2010 Posts: 252 Shop Shark | | Shop Shark Joined: Sep 2010 Posts: 252 | I have just changed the differential to 3.55 and it was a great decision. I can now drive up to 60 kmp without feeling like the engine is going to blow up!
However, my speedo needle is not constant. It likes to flucturate back and forth about 3 mph and won't sit still.
I don't know if this was the condition before the switch or if it is new.
Any help?
Thanks
