Changing gears
Well I decided to change to 4:30s from my 3:73s in my 2001 V10. This will raise max fiver weight from 10,500 to 13,500lbs. I'm pulling a 10K 5th wheel. it's going in Thursday and heading out Friday for the weekend. Looking forward to it.
Trying to spread the pain so I'm getting the rears done now and fronts done later in the fall. Not going to need the 4x4 till winter. Of course I'll get them to disconnect the transfer case switch so I won't accidently make that terrible mistake.
I'll give a tow report next week.

You shouldn't tow immediately after installing new gears. It's recommended you do 500 miles of short trips (20 miles) with no load, change fluid, then go another 1000 miles or so before towing.

I wouldn't chance it. Towing puts more load on the gears and they already get really hot when first wearing in and polishing the contact surfaces. Now I do suppose it will depend on how heavy you are towing, but still, not worth it with the cost of a gear install. If the first drive is over 10-20 miles after putting the gears in, stop every 10-20 miles and let the differential cool down so you don't burn the fluid.

I agree with the others...no towing till the gears/ bearings are broke-in properly. Maybe remove the rear drive shaft and baby it home fwd?

Hi Mike,
Actually I'm in another country, Canada.
Haven't got them done yet. I supposed to get them done Thursday but I plan to go camping this weekend so I'm probably going to wait till next week.
For the rear the parts are going to be around $500 plus about 4-5 hours labour.
I'll update the thread when I have them done.

That's kind of what I was thinking. My truck has 160,000 miles and I might replace it next year so it is hard to justify spending a lot of cash......I am excited to hear the results and have some "real life" opinions of the change.
