I bought the car, my dream car at the time, with every penny I'd saved and borrowed for my beautiful silver cadillac with navigation and two tone leather seats! So happy until I find out that the rear differential bushing is a little worn when I initially had it inspected. I was told this was no big deal (n I really grilled them too because I needed to make a smart car purchase) and was told again that it was a minor problem that for the life of the car would only effect driving comfort and make no difference or damage to the engine or anything else (I was told that by two different service guys at dealers on multiple ocassions) and now... Now at like 107 miles (bought it at 89ish) the jolt when changing gears damn near could give you a concussion from throwing you head toward the windshield(-little exaggerated but its B A A A D, really bad!) and my check engine light is going crazy and I was told that because of the clanking from the bad bushing I need all new engine mounts and by the same mechanic who told me about the engine mounts said I also have an transmission problem resulting from the clanking of the engine, also my suspension(to me at least) has gotten significantly different since the clanking got really bad. And, I just got an oil change at the dealer about two n a half weeks ago and I had to put right over 3 quarts more in yesterday! (Thinking that the violent clank could have cracked something in the engine and now have a leak?? I SERIOUSLY do not have the money to just listen to some more bull that somone tells me then beg borrow and steel (not literally, but almost) to listen to whatever they tell me next and just pay a rediculous amount for who knows what! Does anyone know a good solution to these problems? Had them in the past and know of an affordable way to deal with it?? I know cars cost to maintain but all fuses different stories and no suggestion of a cheaper way to do it? I'd LOVE to know what the actual solution/ problem is and buy the part where I could find it at a good price then pay whatever is needed for labor to instal. Or I don't know, ANY HELP OR SUGGESTIONS WOULD BE REALLY HELPFUL!!! Thanks!!!! :-)
