gear ratios

[waggy]

does anyone know where i can find all the different gear ratios that came on xj's cheers

 

[sidriptide]

an FSM would be a good place to start... (factory service manual) any particular question on gears?

4.10
3.73
3.54
3.31
3.07

Not all ratios were used in all years, and certain ratios were used only with specific engine & transmission combinations.

sure they did. Most all the Automatics from about 87 up had 3.54 / 3.55 in them. at least with a 4.0.

3.55 / 3.54 wont matter....they are compatable...

Yeah - I've got three of them. The oddball is my 88 5-speed, it's got 3.07's (which I'm going to fix when I finally get a couple D44's...)

Your understanding of axle ratios is slightly flawed. Effectively, 3.54 and 3.55 are the same thing.

The ratio is calculated by dividing the number of teeth on the ring gear by the number of teeth on the pion gear, and rounding to two decimal places. Because (for example) a Dana 35 has a smaller ring gear than a Dana 44, the number of teeth to achieve the "same" ratio is different. As long as the ratios are not more than 1 percent different, in operation there is no problem. This is why you'll usually see the 5-speed 4.0Ls referred to as having 3.07 gears, but sometimes 3.08. It depends on which end of the vehicle you're talking about.
