98BlazerLS is an unknown quantity at this point
Default loud thump going from 4-Hi to 2-Hi

Just as the title says.

The truck in question is a 1998 Blazer 4x4 4-door auto 4.3L.

When I am in going into 2-HI from 4-HI, the front end gives off a violent clunk/thump. Usually, when I disengage the 4WD I am on a dry surface and try to keep the truck under 20 mph. I have driven this truck for 10 years, it never did this until recently. I do know that all 4 shocks are in dire need of replacement, would that have anything to do with this problem? Any suggestions?

Thank you
Jason
