Thread: vibration under load

im getting a vibration under normal/moderate acceleration and im stumped as to what to look for next. Ive replaced both front hubs (both were shot) the front driver axle, both lca's and the tie rods. It was aligned after all that but when i get out of first gear into second its starts to vibrate/shake the car, and it does it through second, third, and when cruising in OD. any chance a bad motor mount, or dog bone mount would cause this? I flipped my dog bones and it looks like it may be ripped inside but its hvrd to tell when the bushings are still in. any input would be greatly appreciated thvnks guys

tires were balanced when i got them at the beginning of the winter, im havent considered them seeing as it you coast after moving (no throttle) it doesnt do it, its smooth as ever, only when theres any load on it, unless your really in the throttle, and it goes away in high (>5000)rpm. the motor mount, and trans mount were replaced (used with 80k) but new to me when i got my donor motor but i havent got under it to check them out real close yet seeing vs it finally got cold here lol. but im thinking its probably time for new dog bone mounts, and motor/tranny mounts.

I had a vibration issue. The vibration would only occur during any acceleration, but no vibration coasting or breaking. I did the same things you did and the vibration remained. I went through the balancing and alignments a few times. I didnt think it could possibly be the tires seeing that they only had 10k miles on them. That, and the dealership telling me they were fine. I came across the solution while trying to find a cool location to take pics of my car. I happened to pick up a shÃ*t load of nails in my front two tires and limped the car to the tire shop and had them replace all of them (I dont do mismatched tires). Once I got the tires on, the vibration was gone. They told me that all the tires had "broken bands" in them and needed replaced anyway.

no way? well i guess ill have to give it a shot then, i guess i can throw the summer rims on a little early this year and see if anything changes. thanks for the input
