My brother ha a 99 F-150 4.6L. he bought it used, how can we tell wether it has 3.38 or 3.55 gears L/S???

 

Get the axle "code" off of the sticker inside the driver's door and search the codes here or post it -or- crawl under and get the "actual" code off of the rear end cover (a tag on one of the cover bolts).

------------------
2000 F-150 XL, RC, LB, 5.4L, 4R70W, 3.55LS,
Class III tow, Payload #3, & Convenience pkgs.,
4-wheel disc/ABS, Chestnut/Parchment 40/60,
Ford bedliner w/Paintsaver & gas/wheel/spare locks,
K&N F.I.P.K. w/Outwears pre-filter, Superchip,
Dynomax ultra-flow welded 3" cat-back w/ 3" Y-pipe,
Hellwig front & rear anti-sway bars, Rancho RS 9000s,
Mobil 1, K&N oil filter.

 

Excuse me for being and ignorant rookie, but where do I go to search for axle codes? Mine is H9. Thanks

Put the rear end up on jack stands so the tires are off the ground, turn the truck on and put it in drive, if both tires spin you got the limited slip, right????

Well that would work wouldnt it? but it would probally be easier to just get the codes off the net somewhere, and im wonder too how you do that. Thanks,
Brian

I found a chart of Ford axle codes at www.ford-trucks.com/articles/axlechart.html.
The axle code can be fond of the drivers side door-jam. Hope this helps
