My 2010 SE has about 182k hiway miles on it, and it's developed a definite clunk when hitting a bump, particularly when cornering. It handles fine, the motor is strong, there's no excessive tire wear, but i suspect it's time for some suspension work.

I'm not unfamiliar with suspension work, but my experience is with 50 year old cars. I haven't done much with this front wheel drive car other than a tune up and replacing brakes. Suggestions?

Check sway bar end-links. They are a pretty common wear part and cheap to fix.

Edit: The front suspension is a modified coil-over macpherson strut design. It's really easy to work on.

It gets more complicated if you want to, say, replace a sway bar, but it's unlikely you would need to do so unless you were installing aftermarket performance parts. Everything else is very accessible.

Got 'em on order

Ordered 2 MOOG kits (my preferred manufacturer) , should have them and get them installed tomorrow. Hopefully this clears the problem up, and thanks for the recommendations.

Better. Not perfect, better

So I put on the 2 new end links on Sunday. The old ones were definitely finished. On one, the dust boots were totally shot and I could make the ends move by shaking the part hard. The other, one stud was so rusted it actually broke off rather than be screwed off, even after PB Blaster soaking, proper swearing, and finally, a 3' cheater bar. It was pretty much toast as well (broken stud aside).

Things are definitely better. Not perfect, but better. Most of the places where I would hear a loud, definite, clunk sound are now quiet (just normal suspension groans). However, there still are a couple places where it get a mild clunk now, nowhere nearly as severe as it was before. The car does have a more solid feel to it on bumpy roads (lots of major interstate construction where I drive at hiway speeds).

I don't know that the remaining clunks are anything to worry about, but at the same time, I would like to get rid of them if possible. At 182k miles, I'll pretty much guarantee the front shocks are original, so maybe the suspension is simply bottoming.

Thoughts?

Do some searching of the threads. Lots of opinions on replacing struts vs. "quick struts" etc. At that mileage, they're certainly past their lifespan. I replace endlinks with Moog, and struts with Gabriel "Ready Mount" a few months ago, and the difference is noticable and worth it. I only have 118k miles on a 2010. There is still an occasional creak but I think thats A-arm bushing or something. It is not bad enough to annoy. Also sometimes incorrectly installed brake hardware can make noises over bumps (had that once also).

Well, I went ahead and put on the Gabriel Ready Mount strut kits and they've pretty much cured everything. The car has a much better feel to it, and the clunking/thumping is pretty much gone. Just some normal suspension sounds now like you get from any economy unibody car.

The passenger side, which is where nearly all of the noise was coming from, was shot. The boot was buggered up, and you can tell the strut was at the end of the road. The springs were probably OK, but given the age etc, I would say a lot of the mount parts etc were probably shot, so the complete replacements for about $65 more (total) were worth it.

I thought about doing the LCA/ball joints, but frankly, I don't want to put any more $$$ into the car than I have to. The bushings all look in great shape and besides, I didn't hear anything that sounded like a ball joint, nor did the wheel wobble at all when I gave it the ball joint test.

The car is great, I've been really happy with it, and it's actually in really great shape, body-and-interior-wise, and really mechanically as well, but it does have 182k on it. I bought it for a 75 mile/day commute, and it runs very well. I'm going to run it until the wheels fall off, and hopefully by then I'll be retired and not have to care.

Thanks for all the good recommendations and help!

My install experience with the end links and ready mounts went well. I don't usually do work on my own car to that extent, but it was worth it it. Just had to go very slow. Big savings vs if I had a shop do it. Before winter I plan to do the rear shocks as well.

Did the rear shocks a couple of days ago and they were the final piece of the puzzle. The cars handles and rides SO differently! Quiet, more stable, and it sneers at badly damaged hiway that's being rebuilt for 40 miles round trip per day in my daily commute. I've always liked the car, but never drove it before with a new suspension under it (had 48k on it when I bought it).
