I've had the intermdediate steering shaft lubed in my '02 Bonneville at 30000mls. I'd heard about this issue in several other mid and full-size GM cars, but so far thought that somehow I'd be luckier. Anyway, I wonder if the lube kit contains a grease that won't dry out. Would anybody be able to say?
Now, another issue that has been endemic to the H-bodies is a resilent vibration at a specific speed, between 65 and 70MPH in my case, that refuses to go away with wheel balancing. After replacing loose tie rods, the issue was still there, and after road force balancing, the dealer concluded that the tires were bad and that they'll be replaced under warranty. So far, so good. But is this the actual fix? Now, to those who work in the dealer service area, can I get to choose the tire of my liking, must it be like the original tire or must I accept whatever they get?
TIA
