Source of my clunk solved.

The idiot before me, i.e. : the original owner, has changed axle gears on only ONE axle and the mf'er didn't have the decency to tell me ahead of time. I've been on the phone with Purvis Ford since I dropped off the truck an hour ago, who surprisingly already have it in the shop. The original 4.88's are in the front while is has been discovered the rear has 4.10's. So now I'm forced to pay for a gear swap. I'll put the 4.10's up front, I don't have a problem with that. I'd like to know what to expect cost wise. It's an '08 450. What cost range can I expect with a gear swap? I've never had to have one done so I have no idea, but the dealer service writer has already said I could probably get it done cheaper than they can do.

Don't know what a dealer will charge, but with gears and install kit, as long there is not a carrier break. I would charge about 800-900

That'll equate to about $2,800 in dealership money's.

LOL!! That's about right. Only about a 3-4 hr job, unless there are other problems.

I would get aftermarket gears, Yukon, superior, precision. Gears from the dealer are high $$$. Should be a straight forward install, it's just a dana 60.

There is a break. The original gear is 4.88. I'll let y'all know what I'm quoted as I make my calls. I'll be shopping around over the next two weeks. I need this done now. There's some places near my house. I'm also open to suggestions for shops in and around northern Va.

Well I did a little digging and I forgot it was a super 60 in the 450's. 10" ring gear instead of the normal 9.5" 60 gear. I looked on Randy's ring and pinion and it's $700 without the carrier. So I'm sure your looking at $1000 just in parts.

I would suggest local 4x4, off road, or driveline shops. You can get some of the money back by selling the 4.88's and the carrier.

Good luck

Dropped off the truck today for the front gear change. Took it to a shop recommended by my neighbor who owns his own shop. I was worried to death but the guy pretty much made all my dreams come true. Out the door I'm estimated to be around $1500-1700. As soon as he told me that, I gave him the key and called for a ride home. There's even a possibility it'll go a few dollars less. The r/p was quoted at only $225. Nice. I'll let you know when I get it back. It'll be so nice to be able to use my 4wd switch finally.

Metalingus,

What kind of RPMs are you turning at 65 with the 4:10s? I have been debating the gear swap, or an overdrive. And how is your mileage on the calculator (not the Lie - o - Meter) if you've done it?

In OC, CA, traffic moves bumper to bumper at 80mph and as soon as I get over 2000 rpms (63mph) I can almost see the gas needle physically moving to E. I am constantly in the slow lane trying to hold it down to keep the fuel mileage up (governor-ed at 73mph anyway). On a long trip at just under 2000 rpm or less I can get 16mpg, at 22-2300 I get 8-9mpg....

4.10's with 255/70r19.5's and a .71 overdrive will get you 2000 rpm going 65.
