Ok. So my front diff has been leaking from the front pinion seal for quite some time. I have taken it to Ford many times to have them try and fix it but they can seem to get it right. Also it has been making a clunking noise for a while now too. I have been trying to be easy on it by not offroading and just driving it to work. The noise only happens when I'm rolling back and I start to roll forward. It is defiantly because you can see the movement in the driveshaft. I'm thinking there is too much backlash in the pinion shaft. I was going to have someone just rebuild it but I have been waiting until I paid off some of my credit card. So today I was bored and I just happen to look on ebay and I found one for $250. I figure I can just swap it in myself when I get it. It only has 22K miles on it. I haven't checked around here for any because I figured they would be super expensive. Should I just buy it or rebuild mine? I don't plan on getting a locker or regearing.

 

Well I bought the new diff. $290 with shipping. I hope its in good condition. Wish me luck.

 

i guess ill wish you luck

 

wish ya luck! I've been leaking out of it for a while now too. having it superlifted makes it nice an easy to check the fluid level now too. lol.

 

Well now that I bought it and I still have it out of the truck, do you guys think I should lock it up? It's only $250.

 

lockers FTW.. you need like 1/3 of the throttle

ask Casey how much better my truck performed than his and the guides when we went wheelin mainly attributed to the locker

 

yea but i still pulled you butt across the park....lol

 

you had mud terrains and more power.

let me get my front driveline in and we'll go again.. with 10lbs in the ol' trusty MTZs lol

in low we didnt go either way i just tore the **** outa the ground and made a cool design lol

 

i dont have more power. we both have the good ole 3.slow....ill run 12lbs in the bfgs and still pull ya HAHA

 

What should I clean the inside with? I'm sure there is nasty old oil in there.

 

I use just WD40 or something similar. Works fine.

 

actually i have a 4.0

just has as little power as a 3.0
the automatic part also gives you an advantage

 

oh i thought you had the 3.0....that sucks for me..
