So I had major shaking down the hwy. It was like the death wobble ?. Has anyone else experianced this? I have had the shaking before but when i stopped it then went away when I started up again. This time it did it all the way home and I stopped about 5 times.
any ideas?
If it does it tomorrow on my way to work i am going to take it to toyota.
So mad at my rav 4 so many issues with it.

Is this a new problem? Have new tires just been installed, or have they just been rotated? Does the wobble occur only while driving on the highway? It could be a wheel and tire out of balance or a tire which is not truly round.

I have had the problem in the past after I cleaned my brakes but it went away after I stopped so I was thinking maybe that time was just the brake realigning.
Yea it happens at around 90 km/h where its so bad I have to pull over. About a month ago I got my tires balanced.

Does the steering wheel wobble? Is the wobble in the seat? Did you look over your tires and check your lug nuts? Did you recently drive in any mud or anything that could attach to the wheels and throw off the balance?

The wobble is in both the seat and steering wheel. I will check my lug nuts this morning and my tire pressure just incase its a low tire. No i have only been on clean dry roads.

Perhaps a hanging brake pad on a rotor that's too thin, overheating and warping?

Since you've provided no clue whatsoever as to the year or edition of your RAV4, if you happen to have a 4WD version could it be the rear drive shaft is out of balance or the U-joints on it are bad?

.

Sorry I guess thats important info. Its a 2008 rav 4 4cly engine and is 4 WD.

I checked the lug nuts and tire pressure all is good. Lug nuts are on tight and tires are full of air.

So just an update. I took my rav into toyota and they said they had a rav 4 with similar symtoms and hers was a caliber issue.
Does anyone else have experience with this?

I have had a caliper lock up before but not on my rav and it didn't really cause any shaking...this would be very easy to prove tho if it does it again...once it starts shaking going down the road immediately pull over (pay attention to effort needed to get it to stop)...once pulled over use the back side of your hand to touch all 4 wheels...if a caliper is getting stuck one wheel will be significantly hotter than the rest...could also be a brake hose collapsing and not allowing brake fluid out of the caliper...

There is no difference in the effort when pulling over. The brake did make some noise when stopping. They are new brakes maybe 6 months old.

Is that it? You need to have someone actually look at your brakes, not just offer a guess. Brake calipers have pistons in them and they will stick if not properly cleaned and lubed / serviced and re-assembled properly.

Yes that is it from toyota. My car wasn't doing it when they got around to seeing what was happening. Its a very random thing. Also it hasn't done it since then. So it might just be the caliber some how got out of place or stuck then fixed itself.
They did preform the touch the brakes to see if there hot test and the mechanic could touch the rotor with his fingers. So my brakes dont just get hot. But he did notice excess brake drust on the front driver side brake.
I know when I took apart my brakes before the caliber pistons were abit rusty but I cleaned them up and put the proper brake greese on them. I guess I will just need to service them again to see if that was the issue.
