Mitsubishi Transmissions & Drivetrains Repair Questions ...

Front CV joints, especially if the thumping is worse when turning to the left or right.

I'm not sure what you mean by "Thumping". Please explain if this thumping is engine or body related. Try to describe the symptoms with more detail. Thumping to me, could refer to a Random Misfire, Internal transmission failure, Using the 4WD while on the wrong road surface or the tires are not all the same size, a defective U-joint (in the drive-shaft), a defect inside the rear drive-axle (ring&pinion), maybe a defect in a tire (not balanced or a bubble in the side-wall or tread), wheel bearing, ball-joint, tie-rod, or a needed alignment (observe if the vehicle pulls to one side and look for irregular tire wear). Let me know, good luck.

Try balancing & rotating the tires. If the sound is gone, problem solved. If it is rotated to a different spot theres the answer

My thought would be to look at the u joints and drive line. When driving the car and it makes the thumbing sound shift to natural, if the sound stops it is probably in drive line.

Well if it makes a thumping noise when you drive it is bent. If you hit something hard like a curb it could very well be out of alignment. If you notice the car seems to also go up and down while you drive it probably has a bent axle. Dangers of a bent axle are that it can superheat and break and cause a lot more damage and you might injure yourself. It's probably not a bent axle if you pulls or lists to the side. That is caused by poor wheel and tire alignment.

Might check, Bushing on Control Arm, Top Plate, Shock Absorber !

If its a front wheel drive, check to see that your cv joint hasnt failed on the front axel. Easy way to check is jack it up in park tire should not rotate

Coould be your ball joint. One way to check to see if it is the bearings is to jack the car and grab hold of the tire and give it a twisting motion, one hand on the top of the tire and one hand at the bottom...push/pull type method. You should have almost no play in it whatsoever. Inspect your ball joints. Look for torn boots....means no grease.

If you replaced only one strut, it would be advisable to take the car in for a front end alignment.

Let us know what you find.

this noise sounds like your right cv axle. wou might want to have that checked out, they can do great damage if broken while
