Suggestions on going to 33s?
 

Well, I'm writing this from Iraq so I don't have the liberty to get
under my Jeep right now, nor do the research that I'd like to do to
get this right; that's why I'm asking you guys. I'll be making the
switch to 33x12.50s when I get home on my 89 YJ. I put in 4.10s front
and rear and put it up 4 inches before I left, but my question is,
what else do I absolutely need to do to make this go right? Also,
what else would be nice to do after put these on. I probably go
wheeling (when I'm not deployed) about once a week, and I live in Ft.
Drum, NY. I would appreciate any suggestions.

Sounds like you are on right track other than if I had planned to run
33's or bigger i would have opted for 4.56's instead if you plan to
play hard off road or hit sand too.. Many consider a 4.10 the gear to
hve but the proper gear to have dependes on tires size, vehicle and
engine and there is no universal "good" ratio. One more thing, watch
Ujoint angles on drive shafts as it can lead to vibration and short
Ujoint life. If issues develope, consider having after market CV's
installed in drive shaft which I would tend to do anyway on a YJ with
a 4 inch or greater lift. BTW, nice choice of vehicle as I like those
old Jeeps with leaf springs in all four corners as the newer ones
without then just do not look a "Jeepy" to me.

If you started with 3.73 gears and 30 inch tires then 4.10 is right on
for 33s. To make it absolutely right you might consider getting a
slip yoke eliminator and a new rear driveshaft. I recommend reading

Re: Suggestions on going to 33s?
 

Thanks with concern to my choice of vehicles. I really do love it.
Since I put it up 4 inches (3 suspension, 1 body) I hadn't noticed any
vibrations, but I'm guessing that doesn't negate it happening in the
future if the U-Joints are going to wear down.
