The Ford F-150 with rear axle code l9 may indicate an issue with the 3.55 electronic locking differential. To determine which axle is affected, check the axle ID tag located on the rear end housing unit. This tag is a large piece of metal typically secured by a bolt. If the e-lock requires replacement, prices can range from $38 to $148, varying depending on where you make the purchase.
The Ford F150's rear axle with code L9 features a 3.55 gear ratio and E-locker technology.
No, neither of the previous responses is correct. The L9 in an F150 signifies that you have Electronic locking 3:73 gears.
I have an L9 with a 3.73 axle ratio. Which ring and pinion size should I go for, the 8.8 or the 9.75?
