spring seats (rubber bushing on top of spring) eventually fail in all Volvos of this vintage, and cause an annoying squeak when you hit a bump.: diagnose by turning top of strut under the hood. Normally you can't, use a wrench on the top nut or just your hand on the disc. If it turns, the seat is shot (compare each side, unless both are shot).
You can buy a pair of new strut bushings on ebay for cheap. Replacement involves removing strut, then disassembling it and having a shop rebuild it with new bushing, or do yourself with a spring compressor (a dangerous exercise, so be very careful lest you kill yourself, lose and eye, etc.). It is absolutely imperative that the spring be sufficiently compressed when rebuilding the strut so that the cross nut does not damage the bushing when installed. If the existing shock was leaking, then replace in pairs with Monroe's (about $65@ and will last 100k miles). Use a Torx drive to hold shock while tightening nuts, and loctite on the two bolts holding steering knuckle. If the sway bar links are worn, replace them using e-bay, again using a torx drive to hold studs while tightening nut.
Not all that hard of a job, but spring compression is fairly dangerous, and perhaps a local shop will do each side for $10-15@.

Had similiar problem with local shop strut replacement (I live 60 miles from Volvo dealership, and they are at times a bit arrogant) I also had local guy replace spring seats and one soon failed. Not trusting them further, I replaced the next one myself, and found how delicate is the assembly process when tightening the cross nut. You must hold the rod firmly with a torx driver, and not let the rubber portion of the bushing act to stabalize the main rod when tightening.
However, I think the main problem with premature strut bushing failure is that Volvo strut springs are difficult to fully compress when changing the cartidge (measured length should be 11 1/2 in or less when fitted). If not done properly, the spring seat (bushing) will not slide down fully on the rod, and you then damage the rubber when forcibly trying to tighten the cross nut. This is probably what the inexperienced local guy did, and partially tore the rubber.

Jake is 100% correct.
