eBay under Chevy rear ends
want to know what rear end it has for a replacement
Look at the front part of the rear end where the driveshaft bolts to it and you will find it in the housing. It will be on the passenger side of the rear end housing where the driveshaft hooks to the rear end.
That will depend on which differential you have. There is more than one. Find the metal tag located under one of the differential cover bolts on the rear end housing.
The 3.73 rear end in a 1998 Chevy Silverado 1500 does not automatically mean it is a posi-traction (posi) differential. Posi-traction refers to a limited-slip differential that allows both rear wheels to spin together for improved traction. You would need to confirm with the specific vehicle's build options or VIN to determine if it has a posi rear end.
Inside the rear axle.
Part of the rear end.
Only off a cliff; if your differential siezes your rear end falls off a millisecond later.
It doesn't work that way. There isn't a rear end "digit".
Yes, that would be the easiest way to find out.
The rear differential is a part of the power train, not a part of the suspension on a vehicle. It is the suspension system you need to be investigating on your vehicle. You more than likely have a broken spring.
That is a 1965 Chevrolet Chevelle 12 bolt rear differential.
