Does anyone know what might be the cause of my Z veering to the right over bumps/potholes?
When my passenger side rear wheel drives over a bump or pothole it'll veer over to the right and wobble back into place. It doesn't happen when the left side drives over a bump, instead it stays stable when that happens.

Thanks in advance.

 

Could be worn shocks with poor rebound qualities. How many miles are on your current shocks?

 

I wouldn't know, I bought the car about a year ago, haven't changed them since I bought it. Is there any way to check the shocks to see if they're the source of the problem?

Edit: Since buying the car, I know I put on 10k on it, but I am not sure about the previous owner

 

What’s overall mileage on car?

Get under and check for the mfgr markings.

If they’re OE shocks and you have more than 50-70k miles, they’re pretty much toast.

But in addition to possible bad shocks, there could be (probable) front suspension wear... control arm bushings, steering linkage, etc All prone to wear and aging. You didn’t mention the year of the car but at minimum, its ten years old and up to 16! Things wear out.

If you’re not able to diagnose, take it to wherever You get it aligned and have them check the front end. (Not guesses but “OK, if you think it’s that and you replace it, that had better be it.”)

 

Overall mileage is 120k. But the previous owner installed coilovers and I'm not sure what brand, nor how old they are/how many miles are on them. Its worth noting that I took it to a mechanic recently and he found that the passenger side rear coilover was on backwards, (which was causing a ticking noise).

They've since been reinstalled correctly and the ticking sound was fixed, but still do the wobbling thing described in the OP. I suspect the rear passenger coil may have worn from driving on an improper installation.

 

It's worth mentioning that any lower bushings control arm sway bar dif etc are pretty worn out if they havent been replaced. Mic's right. Check the shocks first. But a bunch of urethane bushings are good for business.

 

A bad toe angle could cause the wheel to grip in a certain direction after hitting a bump.
