So I bought a 1993 YJ the other day and noticed something a little different about the front axle. It looks bigger than my old 1993 front axle, and it has spring perches on the top and bottom. The gear ratio stamped on the pumpkin says 4.10. My rear axle ratio stamp says 4.11. Is this cause for concern? I believe the front axle is a ford 8.8 but I am not sure how to confirm this.
A little more info on the jeep:
She is a 4.0L, Manual, with a 5" lift and 35" MT's. She easily does 60-70 MPH on the freeway in 5th gear without going over 2500-3000 RPMs.
Also, is there a way to check and make sure the speedometer gear was changed?
Lastly an unrelated question. Should I be concerned that my temp gauge never goes above the first tick mark after 100? I just drove home from work, which is about a 40 min drive down the highway and the temp never rose to 210. My old jeep always stuck in the middle.
looks like an dana 30 and the plates top mean it was set up for spring over axle.
The rear axle has the perches on top too. It makes no sense why someone would go through the trouble of putting perches on and not do the SOA; that's the most expensive part of the lift!... Not counting the tires... Lol
Thanks for your help! I think i should jack up and double check the axle ratios by turning the tire and watching the shaft.
