You don't mention what model you're talking about or what struts you bought?
I wonder as well if you got the right struts.
Or possibly your springs are warn out. I replaced my struts at 200,000 miles, folk said no need to replace springs, and the rear sagged really bad with adults in the back seat...like it was rubbing it was so low, we had to move gear to the other side for it not to rub (probably just rubbing cladding or something simple). anyway - i replaced the springs.
Baja rear springs give you a bit of a lift....like 1" or something, quite a few threads about it.
