Default Typical to Replace Motor Mounts After 5 Years/70k Miles?

I have a 2008 PT Cruiser Turbo with 175,000 miles.

In 2012 at 89,000 miles, I had to replace the upper motor mount and a year later at 103,000 miles, I had to replace the lower mount.

Today at 175,000 miles, I'm told I need a new "power torque mount" which I assume is the lower engine mount?

So is it typical to have to replace the motor mounts again after 70k miles? If yes, then I might as well replace both (need new lower front control arms replaced too).

Thanks for your feedback!

Frank

My motor mounts have 100,000 miles on them, working fine, but showing signs of getting tired. A turbo will make them wear out faster. A standard trans will make them wear faster. The quality of replacement parts varies.

My advice is to change them both at the same time, from the same manufacturer. And make sure you adjust them to the correct dimension before you tighten them both down so that each rubber bushing gets equal stress. Tilt the motor back, don't lift it. ----- They are called motor mount struts, upper and lower.

It depends on the quality of the parts that you got and if the shop, or yourself, followed the torque strut adjustment procedure when they are installed.

Also, the upper and lower should probably be replaced at the same time, since they work together, and if one wears out the other can't be far behind because the good one has to work that much harder to make up for the weak or failed one.

Replaced mine on my 2008 PT this past summer at nearly 80000 mi. Lower was torn and upper looked shabby.

Replaced the top and bottom at 80k miles when I bought the car. 2 years later and 20k miles and I had to replace the lower one again although it may have been good for another year or 2. They are $10 each and take 20 minutes to replace so it's not a big deal. The biggest effort is ensuring the spacing on the top strut is correct. The top is in good shape so I only needed to replace the lower one. Autozone sells them for $40+ but has a lifetime warranty. I doubt I'll need to replace it 3 more times so $10 a pop isn't too bad.
