94 xlt, 2.3l, 5 speed manual

My speedometer/odometer runs 16% slow. Have to put it at 58 to go 65. 200 miles on the odometer means 232 miles driven. (checked by gps) I pulled the cable out of the transmission and counted 19 teeth. So I figure a 16 tooth gear will work (84% of 19 is 15.96). The cable goes in on the drivers side. Is this the gear I need?
Thanks.

 

Yes, that would probably work

Manual trans uses 7 tooth drive gear
You need your tire diameter in inches, enter info here: https://tiresize.com/calculator/

Rear axle ratio is on drivers door label, back edge of door, can look up the code here: https://www.therangerstation.com/tec...le_codes.shtml

most popular ratio was 3.73, and with 27" tires then 19 tooth driven gear would be correct
you would need 32" tires for a 16 tooth to be correct

 

The sticker calls for 225/70-14 tires. It has 205/70-15 now, which is almost identical in diameter. The sticker says the axle is 84, which the chart reads a 3.45 ratio. I got the pickup a year and half ago, the previous owner inherited it and didn't know much about it. The speedometer gear calculator says 18.5 teeth as to the setup the sticker calls for, so a 19 tooth gear. But fiddling with the numbers to achieve a 16 tooth gear, it's close to the axle being a 3.08 ratio. Makes me wonder if the axle was swapped. Or the wrong axle installed and the sticker is wrong.

Anyway, am I correct in thinking I need a right hand gear as it is on the drivers side? I'm thinking the one from Amazon above is RH.

 

Ford gear is what you need, not sure if they were ever designated as LH or RH, or I just don't recall that

If you ever jack up the rear axle(to do rear brakes or ??), you can determine rear axle ratio at that time
Put a chalk mark at the bottom inside of each rear tire so you can see it from driveshaft
Put a mark on drive shaft near differential
Turn the drive shaft 1 full turn, one tire should turn, some times both but in opposite directions
Repeat same direction turn of drive shaft another full turn
Then one more full turn for 3 full turns
If the one tire's mark is at the bottom then its a 3.08 ratio
If you turn the driveshaft another 1/2 turn and its at the bottom then its a 3.45
i.e. 3:1 ratio means drive shaft turns 3 full times for 1 full turn of axle, so 3.5:1 means 3 1/2 turn for 1 full turn of axle

OPEN differential only powers one wheel at a time
Limited slip(positraction) power both wheels
