Does your MkIV Jetta, Golf or Beetle make noises when going over bumps and rough roads?  In this video Corey from IDParts shows you all the bushings and links to check on your own car to identify the problem.

Hi, I’m Corey from idparts. In this video we’re going to do a suspension check on a Mk. IV TDI. On this car we’ll be checking the following:

  • Strut Mounts
  • Ball Joints
  • Tie Rod Ends
  • Sway Bar Links
  • Control Arm Bushings
  • Rear Axle Bushings

OK—the first thing we’re going to check are the front strut mounts. They’re located underneath the hood in the top corner. It’s got a black cap which is the top of the whole strut assembly and the mount is located under this metal area. You can tell how worn the bushing is by how much gap there is between the metal and the black cap. On this car, the gap is very small because these were recently replaced. Whenever it gets above 5/8 of an inch or so, the front strut mounts need to be replaced.

  Now, we’re going to check for play in the wheel side-to-side to see if the tie rod is bad. No play here. Now we’re going to move it up and down. If it has excessive play, that means the ball joint is bad. No play there either.

  We also need to visually inspect the ball joint for any cracks in the boot. If you see any oil or grease that’s falling out, that means the ball joint needs to be replaced. We’re also going to check the tie rod end for grease or oil leakage. No leaks.

  Next thing we’re going to check is the sway bar link. The two ends look sort of like a dumbbell. We’re going to check for cracking in the bushing. This one needs to be replaced—there’s a lot of cracking. What will happen is when you go over bumps there will be a loud clunking noise.

  The control arm rear bushing is located here, underneath this bolt. Again, we’re looking for cracks. This is an Audi TT style bushing because the rubber is sold & doesn’t have any holes in it. Nearby are the subframe bushings, which also need to be checked.

  The last thing we’re going to check is the rear axle bushing. This beam is the rear axle, and the bushing is located in this bracket just in front of the wheel. If the bushing is cracked, the real axle will make a lot of noise going over bumps. If you see the bushing separating from the outside housing, it needs to be replaced.

  So that was one side of the car, and at home be sure to check both sides. Thanks for watching.
