Hi,

New to the forum. I have a 2001 1500 5.2 4x4 with a 3.55 gear ratio.

Apparently, my front diff is shot (according to mechanic, who said it would cost me about $3,000 total for parts and labor to fix the front diff). This means I would need a rebuild.. but I don't know what I need for this. I saw online that there are Ring and Pinion kits, master rebuild kits (which don't include a ring and pinion), and some other kits.

If I wanted to change the gear ratio, would I just need to change the front and rear Rings and Pinions?

Also, does the rear 3.55 diff. come stock with a limited slip differential (LSD)? If not, how would I install this and how much would it cost to do so?

Thanks for all the help in advance!

First off, that's a really high quote. Buddy of mine just had his 2500 regeared front and rear for $1200. I'd definitely get a few more estimates

Yes, front and rear gear ratios must match.

You can see if yours came with the ls by looking up your build sheet. Go here http://www.ramtrucks.com/webselfservice/ram/index.html?screenName=customer&country=us&emailUrl=goToEmailForm%28%27R%27%29 click on "Equipment Listing" on the left, enter your vin, and it will give it to you instantly.

Since your in there already I'd upgrade to a Truetrac and it shouldn't be much more over the regular regear price

Thanks for the info... If I upgrade to the Truetrac, will I still need to rebuild? Or does it replace those gears?

A Truetrac just replaces the ls, you'd still need to regear
Ok I did the Build Sheet by VIN thing and now this is the information I have:

Front & Rear 3.55 axle ration
Dana 44 195MM Front Axle
"Corporate 9.25 LD" Rear Axle
NO Limited Slip

Now, where would I find these rebuild kits? I saw some online, but I've seen a lot of similar ones with minor differences and am not sure which to get.

Where is the best place to check out the Truetrac also?

Thanks again

Ok, so, I looked into the Trutrac and decided to hold off on that for now. Also, I am going to keep the stock gear ratio (3.55) for now. I did find the parts I need to completely rebuild the front differential. Here they are:

1. http://www.morris4x4center.com/differential-gear-set-4778595.html (this is $200 cheaper than the Mopar brand parts)

2. http://eastcoastgearsupply.com/i-16500959-yukon-dana-44-3-54-ring-pinion.html (this is a couple dollars cheaper than the Dana brand parts, and supposedly heavier duty)

3. http://eastcoastgearsupply.com/i-126957-dana-44-install-kit-master.html\

_______

Since the rear diff is operating fine right now (was rebuilt by Jasper a while ago), I am going to leave that and just rebuild the front. Thanks!
