Default New guy with 06 fx4

hey guys. this is my first post. i just picked up a 2006 f-150 fx4 this last weekend. its got 52k and all stock. ive been doing some reserch on mods. lots of different options. the only thing i dont like is the rear gears are whining from around 38-60mph. any cure for this? its pretty loud.
also, from these pics, do you think i need to level the front?

Welcome aboard! Always good to have new members.

As to the rear end whine, it might just be that it needs an early fluid change. This is usually recommended aroung 75K, but perhaps your's was slightly abused by a previous owner, or maybe it was used to tow. Have it checked out by a qualified tech for advise; get a couple of opinions from the techs. It's difficult to diagnose that type of problem on an internet forum.

Level kits are cheap and easy to do, and the general opinion on this forum are towards the "pro level" side.

Again, welcome aboard. Nice truck! FX models are a popular model here.

Welcome to the forum!

I agree with Bucko, definitely change the fluid before resorting to replacing the ring and pinion. If you do have to R&R, you may want to consider adding a LS or locker if one is not already installed.

I personally prefer my truck to have a rake, that way your not squatting in the rear under load. You can fit up to 33x12.50s stock, if you want to go bigger on tire you'll want to level it.

Depends on the tire sidewall aggressiveness and width, check out the tire fitment sticky at the top of the 04-08 Forum.

I had 275/70R18 (33.2x10.8) stock with no rubbing.

I would definitely go with black, especially since your truck doesn't have any chrome on it now.

Not a big fan of the bull bars, I believe with most of them you will lose your front tow hooks.
