I went to a driveline repair shop here in Atlanta to get my U-Joints replaced (car only has about 110,000 miles on it) they also found that the transmission Yoke was worn, there's a groove you can feel (and hopefully see in the picture, it's towards the right side, near the ....dirt) They actually had a nice used one to put in, and did a great job balancing everything, but were of the opinion that I should get the bushing in the output shaft housing (IIRC) replaced probably in the next feel weeks. Thing is, I am a bit short on funds right now. I was going to ask at the transmission shop next to their business what they thought, and the cost, but they didn't come out of the next room (they could hear the bell as I came in) so My Dad called a transmission shop near where we live and the guy he talked to said it would cost a few hundred dollars, crossmember would have to come down, etc but that really I'd only have to deal with fluid leakage, that it wasn't that important ! I am confused at this point, is it really important? am I going to beat up the new u-joints, or harm the transmission? oh, I forgot, the vibration I have been dealing with off and on at highway speeds on the way to work, got VERY bad last friday as I was almost downtown...pulled over before it would really be hard to pull over, checked tires for tread separation, etc. didn't find any issue. decided to head back went to brake guy we have used for years he drove it, and didn't really feel the vibration. he did NOT think it was U-joints, but had told me awhile ago that I would need u-joints sometime soon. Haven't been back at highway speeds (then bumper to bumper traffic heating things up) thought it could be brake related, guy at brake shop said sometimes a bad master cylinder can cause brakes to grab, and to check temp of wheels, if one was hot enough to burn your hand, that could be the issue, but I had it replaced just a few months ago, so that seems unlikely...sorry for the length here, just wanted to mention this as to why I went to get u-joints in the first place. and that vibration got a lot worse after 20+ miles on the road... hmmm, perhaps photo is too big? will try to upload again after resizing. Thanks.
