Bumping sound from the rear

I have a 1999 Rodeo with 64000 miles. Auto tranny. When I take off from a stop I feel a bump from the rear. It also occurs when I stop after rolling from a speed. The rear shocks are new. There was a bad one and I thought that replacing them would fix it but it did not. Anybody got ideas?

The slip yolk needs to be greased. If you search here for clunk or thump you will find more info. Also, I have more info in my FAQ link below.

New front shocks may help some too.
