The rear end is going out,whats the easiest way to repair it?

If you have limited mechanical skills the easiest way to fix it is to find a good one in the junkyard and replace the whole rear axle. if you do your own brake jobs then you could probably do that. Otherwise you will need to take it to a shop to have the gears/bearings replaced and the rear end reset up.
Of course it all depends on what part of the rear end is going bad. Most shops will do a complete rebuild so your rear end will be like new. While some people will just replace the one item that has gone bad.
Usually when something goes bad in the rear end it contaminates and causes some collateral damage to the rest of it so a complete rebuild is recommended.

How do you remove engine out of a 98 gmc savana van

Older vans required you to cut the front core support and slide it out from the front end. the cross member and front end of that van should unbolt though and allow you to slide it out through the the center if the front end it disassembled. hope this helps!

GMC Rear End Rebuild

here is a great site randy sell great parts at a great price and he is a pro.
check his site and you will find even more info than you need randys
and what emissionwiz said is 100% correct i have had people bring me their trucks with rear ends that they tried to set up just by looking at tooth contact and they have ruined a new set.
follow randys instruction with the right tools and you wonnt have a problem.
good luck paul
