Vibration or ruff running

[Dangerousdave26]

2004 Liberty Renegade
166,000+ miles
It is running ruff or vibrating with moving

This started a couple of months ago. I got to work and noticed the vibration. Went home then next day back to work still had vibration and I was not quite sure what it was. When I parked the vehicle I got a definite clunk out of the area of the drivers side front tire. Well I know what that is bad CV Joint no big deal. I nursed it home slowly around 45 miles per hour vibrating worse than before the whole way.

I bought a new drive axle and installed it. That problem went away but I still have the vibration from the day before the CV Joint raised its head.

Since then I found my front driveshaft was going bad so I replaced it.

The only codes I have had in it for a rather long time are the 2 downstream O2 sensors and a P0452 EVAP System Pressure Sensor/Switch "A" Circuit Low. I replaced the 2 O2 sensors (I had the replacements for a while just didn't get to changing them)

Now the only code i have is the EVAP system P0452. I replaced the gas cap for the fun of it but that was not the issue. From what I read this code shouldn't cause this issue. But I would like to clear it to be sure. Anyone have some clear instructions on where to look for this fix? I have seen references to a sensor on the top of the gas tank but I can't actually find a part.

I went ahead and bought the passenger side axle but I don't think that is it.

I also have a MBRP exhaust that I wanted to install on it after I fixed the O2 Sensors. I am not sure if I should change that before fixing this issue or not.

The lack of a code pointing to a problem has me stumped.

I just ordered 3 Standard Motor Products UF270 coils. i would have ordered 6 but Rockauto only had 3.

By now it is fair to assume at least 1 of them might be going bad.

Well today I changed out the exhaust just to get it off the table. I also decided to remove the rear drive shaft and check those universals. The rear one is starting to go bad, just a small amount of play. Not sure that could cause the vibration but here we go.

I took the Drive Shaft to a local driveline specialist and had him rebuild it. I couldn't get all rusted clips off the caps. I also thought the tube was rusted so bad he was going to have to replace it. He cleaned it up and said Nope it's still solid and good just rusted. He changed the universals and balanced the shaft. This evening I put it back on.

And I am pleased to report the Vibration is gone. Lesson learned for this vehicle even a small amount of wear in the universals can start the thing vibrating.

Tomorrow I will put the transfer case shield back on and that ends this one for now.

Thanks for reporting. I'm also having some vibration issues at the left side (above 70mph) and after replacing both CV axles I'm suspecting my drivelines (probably the front).

there are kits you can get to rebuild the joints of the front driveshaft, example for differential side
