Re: 86 Suburban 8.5 rear axle dumb question ??
In a bbw such as a Suburban you do not want 28 spline axles, and the 30's should be factory.
On 28 vs 30 splines. The actual splines are the same size, but the axle get thicker to accommodate more splines.
You axles carry some of the weight of the Burb, and you need thicker ones to survive.
