Shaking when pressing the gas

Everything was going fine with my Jeep until I took it to get inspected. They had to replace the front driver side u-joint and now I have a pretty intense shaking going on when pressing the gas and am going between 20-55 mph. I took it back and they said it's just the new u-joint and should go back to normal at some point, but I wanted to get your opinions. It only shakes when I'm pressing the gas, and I assume if it was the u-joint it would shake regardless. It's not really noticeable at 65 mph and when just starting off. They don't seem to be concerned about it, but as it wasn't doing this before I am still a little worried. Any feedback would be appreciated. Thanks

sounds like they ****ed up replacing the ujoint
because it sounds like a u joint

Working with cars is a little like a really awesome date: you start out expecting this to be something simple and straightforward; four hours later you're laying under her, panting and cursing, and things are a lot more complicated than you thought.

When my Jeep stops making strange noises, I become concerned. That usually means I have to go back and find whatever fell off.

U-joints that are installed correctly don't vibrate or need to be driven on to get them to stop vibrating. That shop screwed something up and it's likely that they botched the u-joint installation. What a scam the east coast states have going on, automotive garage owners must be laughing all the way to the bank by how inspections work back there.

Gone to Florida 7/19-7/28.
When you have a choice, buy American made.

They told me the only thing that could be done if it didn't work itself out is to replace the whole axle which they would do for just the cost of the part...but I'm thinking I'm just going to take it to the actual 4x4 mechanic up here and just do a new u-joint again or something.

I don't really have a whole lot of time the next couple of weeks to either do this myself or get it into the shop. Is this going to do any damage to drive on it like this? Thanks for the help everybody.

Curious, what are some examples of what can be done wrong to "botch" a u joint installation that would cause a vibration?

For one, you could bend the yoke ears.

That's a big reason why a lot of people will NOT use a press when changing u-joints

Driving on it is not a good idea. Fix it somehow.

I know...I love PA but this inspection crap is...well crap. Haven't had any problems recently until this. The yoke ears don't look bent but I called up the last place and they're going to redo it. Are there any other ways that it can be botched to produce a vibration? The yoke ears don't look bent to me.

turns out it was a u-joint but not the one they changed...hate mechanics...i'm going to assume that they just missed this second one and never go back there again. And that they weren't just doing stuff to bad the bill. Thanks for the help guys
