'88 F150

3.54 E8TA LD

I've gathered that 3.54 is the gear ratio. All I'm confused on is if it's limited slip or not? Any ideas?

Thanks

 

No tag on the door post?

 

very very doubtful it has an LS in the front, they are very very rare.

i'm betting your axle code on the door is H9 which is 3.55 gears and an LS in the rear.
and yes the factory put the 3.54 in the front but the rear has 3.55,

 

There is but Im really not sure how accurate it is based on the manufacture date considering its an 1988 model

 

Yeah I do have 3.55 ls in the rear.

I just can't seem to find details on the front axle

 

the front axle is a "reverse" rotation 3.54 open diff, DANA 44 TTB.

 

Thank you. All I needed to know

 

I have seen exactly two trucks with factory front limited slips. One had a funny axle code, I can check the cab, I think It had two letters then the number. It was an xlt lariat, and probably the nicest truck I every destroyed. You jack up one wheel, lock the hubs and try to rotate the wheel, if its really hard to turn , you might be in luck, If you just spin the driveshaft, Its either open, or the clutches are shot.

Its probably open.

 

Thank you. All I needed to know
