I've got An issue with getting my new control arm bushings on, Does NOT want to slot on, managed to get one about an inch away from where the previous original bush sat. Is there anything i can use that's better than silicone spray? I've bought some silicone paste off screwfix and gonna retry the process tomorrow. Any advice?

The cars untouched, got it at 44k miles and now at 64. most of its life on a driveway. Surely it should be this difficult?
