My kid has a 1995 Bonneville. Very clean, excellent runner with no problems. Except: He already did the intake manifold gaskets and plenum because I read they fail. His were on the edge. A few days ago he found his cradle connections were almost all shot when he was hunting down a steering issue. Wouldn't even drive it when he saw that, so he took my Grand Am. He's replaced them now. Cradle was ok. The isolators, retainers, washers, bolts cost $505 at the dealer. GMPartsDirect cost is $336 but who knows how long before they get shipped, if they'll all be correct, etc., so he bit the bullet at the dealer. Sometimes that's best. I had to convince him, but he's happy with it. Besides, I didn't want to wait weeks to get my Grand Am back. Can't say how common this cradle connector problem is, but common enough that you should check it if you have this era Bonneville or similar cradle setup. Seen it also happens to Luminas/Montes but they are 4 connector instead of the Bonneville 6 connector. I'd welcome any pro input here, because I have a Lumina. Think I'll have the kid put it on the rack before long to check the mounts.
