Struts

i have a 1995 corsica and i just changed the front struts cause the manholes and railroad tracks seem very hard when driving over them but it seems to be no change i did not change the upper mounts could putting new ones in make a diff.thaks for any help

Not really. The upper mounts aren’t really what absorbs the impact.
Have you checked your tire pressure?

just got new tires put on but i think it is fixed because got a front end alighnment and its all better now i dont think the struts were bolted tight
