I have 94 K1500 Blazer, 250K miles, with 8.5", 10-bolt, 6-lug rear end.
At 220K miles & 3 yrs ago, the rear gov-lok differential grenaded, twisted an axle shaft, etc. I had a local repair shop install a used, complete rear end that supposedly had only 80K miles.
When the shop told me they "opened it up to adjust gear lash, clearances, etc" my stomach sank -- IMO setting up differentials requires much specialized knowledge and skill, which most shops don't have.
Over the last 3 yrs, the rear end slowly developed what I think is bearing noise & gear whine -- gotten fairly bad now. The 2 options I'm considering are :
1) Find a competent specialty shop to completely rebuild existing rear axle, and optionally install an Eaton True-Trac diff.
or
2) Buy a complete, re-manufactured rear axle assembly (gov-lok again) from NAPA or Autozone.
Might be able to install it myself, although its weight & bulk could be a challenge for a single person.
> > Any comments whether #1 or #2 is likely to be a better long-term solution?
I don't want to crazy overspend, but $100-200 either way is not a big deal if I get a reliable, long term fix. Planning to keep the Blazer for long time.
Option #1, Finding a competent specialty shop in the Los Angeles metropolitan area, is a challenge. Seems 1/2 the cars on the road are disposable & leased hondas, toyotas, or BMWs.
Any shop suggestions would be appreciated.
This place is 100 miles away, any experiences? http://www.theDifferentialAndAxleShop.com
Option #2, both NAPA and Autozone sell the same vendor's re-manuf axle (gov-lok), an ATK RAXP1513B, with a 3 yr warranty, for $1600-1700.
