If it makes a so called fish tailing on the back end, when going over a pothole, or a manhole ( not sure how you call them), usually on lower speeds, the first thing yo check are the rear axle arm bushings. The car's rear end tends to play when they start to fail. What you described for the high speed, may be something more serious. But check the bushings first. There is a photo of all the bushings.

Hi kacar, your picture is great. Is it specifically for 4th gen Camry? Thanks

DANGEROUS lack of maintenance!

When was the last time the struts (front) and shocks (rear) were replaced? There are a lot of supporting components that go along w/ the replacement of struts/shocks too. It is recommended to replace struts/shocks 5yr/50k mile to maintain OPTIMUM handling and braking characteristics. Badly worn struts/shocks = poor handling and increased braking distances. One doesn't have to replace at the recommended 5yr/50k mile interval, but the tradeoff is bad handling and increased braking distance.

Post#2 is a good start. But there are probably all kinds of other bushings that are worn out too.

If you can DIY, it'll just be time to replace the worn components. Unfortunately the aftermarket companies don't make a comprehensive set to replace ALL the bushings, unlike some other popular modified cars (ie Civic). But they make a la carte kits. Just search "Camry bushing kit" and you'll get various links. Check out Rockauto too and the RockAuto section for any discount codes.

Good luck.

 

I had that condition with my car until I replaced the tires that were nearly worn out anyway, but the particular tires themselves were very bad performers. Still, follow the others' advice to get the suspension checked, but you can just look at the tires to see their wear and make sure they're properly inflated.

 

OP needs to seek paid service advice. Doesn't know enough to properly diagnose.

Please stop driving the car on the road! The vehicle is a danger to everyone else. Its one thing if you get injured/die, but completely irresponsible for you take others w/ you, knowing the car is DANGEROUS.

 

Completely agree with this. Find a mechanic friends of yours trust (or a friend who IS a trusted mechanic) and have them do a full suspension inspection, at a minimum. You need to get professional eyes on the car for what evidently has become a legitimate and potentially dangerous safety issue.

 

Sounds like blown struts to me.
Do the push/rebound test.

At the 2:45 mark.

If yours is bouncy, struts are blown.

Camry's handles like a boat on blown struts. The body rakes/sags like crazy too, which would lead to your description of its handling.

 

Have you checked the rear tire pressure? Low pressure can cause fishtailing, especially if the rear tires are low compared to the front. A tire can look OK, but still be low enough pressure to cause problems.

Also are the rear tires the same quality and size as the fronts? On a trip with friends we had a blowout in West Texas, and we cheaped out replacing the rear tires, buying two that were narrower than what we were replacing. The vehicle was hard to keep on the road until we switched out and put the cheaper smaller tires on the front.
