I have a 1990 Chevy Blazer, 5.7 (350) that just had the rear wheel and axle rod come off while driving down the road. luckily was only going about 15 mph. Trying to find a replacement axel is a royal pain in Alaska. Anyone have suggestions of a replacement rearend, or rebuild. Have access to a full shop and mechanics but have to do the work myself, Mechanics are advisors only. Any suggestions would be appreciated thanks.
You did not say whether the axle came out because of C clip failure or breakage. The simplest upgrade here would be to find a 9.5 inch 14 bolt semi floater rear axle used in some Z71's and LD P/U's. It is often overlooked and the 10.5 inch FF 14 bolt is used. The 9.5 is a LOT stronger than the 10 bolt you have and is a bolt in and usually has 6 lug hubs too, A 10 bolt is a marginal rear axle at best and prone to failure when tires larger than 33's are used and it is even marginal with 33's at times. The 9.5 is about the equal of a D60. Also if you elect to stay with 10 bolt there was 2 type of 10 bolts in
1990. GM was in the process of upgrading them to bigger axle that where 1/10th of a inch bigger in diameter (about 1.18 vs 1.28 ) and they will retrofit into a older axle with a spider gear change because the splines are different. After 91, they all use the thicker axle. (the 14 bolt 9.5 has axle that are about 1.38 inches in diameter)----------------- TheSnoMan.com
