Toyota makes crunching sound at high speeds and bump

Is the crucnhing coming from the front or rear wheel?

What year Corolla is this btw??

Sounds like your shocks.

Toyota year: 2000. It is the front passenger side wheel.

If you go over this dip all the time, or speed bumps at too high a speed, your shocks are going to go to hell, and have to be replaced.

70 mph is pretty fast to be driving over a dip in the road.

I suspect that what is going on is that your front strut (you don't have shocks in your car's front end - you have struts) is rusted in the area outside of the "normal" travel zone. When you hit a big bump the strut compresses beyond the normal travel zone and what you are hearing is the strut grinding. It could also be that some other front end part is doing the same sort of thing but the strut is, IMO, the most likely cause.

The obvious answer is to replace the strut. Well, ok, the REALLY obvious answer is to slow down - but I suspect that isn't teh answer you want to hear.

yeah, struts....that what I meant...

you knew what I meant, right fishin?

Sure, sure! Gotcha covered!

Thanks for the advice. I will definitely have the struts or front shocks looked at. And just for the record, I'm talking about tiny dips on freeways, not drag racing speed dips in front of schools with crossing guards that get me 100 points per hit. I mean seriously, it is a Toyota Corolla, how crazy do you think I am? A Honda owner?

Ball joint. They are bad for going out on Toyota's.
