A while back I had a Heep XJ that had that happen to both front springs. I never even noticed it until I started blowing out exhaust gaskets on top of the down pipe every couple weeks from the front axle hitting the downpipe... I haven't seen it on a kick, though. The 96 X-90 I just brought home was leaning a little to the left. The spring wasn't broken and nothing was bent, but installing a spare spring I happen to have fixed it, so the spring must have been sagging or possibly just a little piece broke off and fell away, although there doesn't appear to be any rough edges...
