I just completed a 4000 mile trip towing about 4200 pounds. Now that it's complete I noticed a weird "chugging" sound when accelerating. Took it into a shop and they said my rear differential is tore up. I don't remember exactly what's wrong with it but he said it needs to be replaced. Is this the normal price for a job like this?

Rear differential work ain't cheap. But that sounds high. It also depends on the shop. I had one shop quote me starting at $1,100 for a pinion bearing. Another shop quoted me $600 to start.

For Alaska that would sound about right if they are replacing all the guts with new.

Wow. A $300 used rear axle would work here. Or $650 for a new R&P, new LSD, bearings and the standard $100-$150 labor for this deal makes me think you can find a cheaper alternative. Even a true-trac upgrade would be cheaper, or a full case Detroit or ARB would be cheaper.

Examples:
LSDs:

Install Kit:http://www.justdifferentials.com/index.php?main_page=product_info&cPath=23_40_158&products_id=3572

R&P:
http://www.justdifferentials.com/index. ... =22_33_103

$650 + labor. And that was going to one site, not comparison shopping.

Hit up your local 4x clubs for a member to do the work for you at home.... You can get this done for much much less, I'll bet. Maybe $800-$900 for an upgraded, not repaired, rear differential.

Wait, so if I could upgrade this to a stronger unit, could you please tell me exactly what I would need to buy and where to buy it?

1st what exactly is needed? What was broken and not reusable?

If a complete rebuild is needed your looking at gears,master install kit,axle bearings/seals,possible axles,carrier/spiders(or LSD/locker),and then labor.Shipping to Alaska is not cheap no matter what you get.

Is the chugging the OP describes a symptom of a tore-up rear diff? Sounds more like a U-Joint to me.

Those links would cover pretty much everything:

New LSD or locker carrier
New ring & pinion
new master install kit
$650 or so in parts.

Got axle seals,axle bearings,and axles to ne included if that much carnage ensued.Your talking closer to $1000-$1200 in parts alone.

or at least not a totally dead diff - I'd look for a second opinion

I don't know if they are in alaska or if theres a place close enough... but you can get a used rear for like 100 dollars and up... I changed my own rear in my driveway in about 6 hours with a couple of friends passing me parts / tools... The first place I check is car-part.com... its a huge list of auto wreckers and sort by price... I find I get the best deals that way.. I go and inspect the parts at whatever yard it is... and 20 / 20 times its worked out GRREAT!
