Sagging rear end

My 2006 touring has a sagging rear end, when I have to adults in the back seat. Is this normal? Do any other Avalon owners have this same problem, is so what have you done to fix the problem.

My '07 squats when I've got a car full of people as well. It's done that from new.

Just the nature of the beast. If they made the springs strong enough to not sag with 300-400lbs of adult in the back seat, the ride while empty would be jarring and uncomfortable, sorta like riding in a 3/4 ton truck.

Good to know about this. Does the car scrap the bottom if you hit a bump or something like that?

Mine never has and that's with three big fellas in the back and two more in the front plus a couple bags of stuff in the back and full tank of gas.

I have to disagree with you, my previous car was a 2004 GS300 now when I would have to adults the GS would lower, but not as much as the Avalon. Now with the Avalon just with my wife who is 5'6 135 lb.. and 4 months pregnant and our 13 month old, the rear squats really bad. Another thing that I have noticed is that I have felt the rear wander sometimes when the road is uneven or there are bad grooves in the road.

No but I have felt the rear shocks bottom out once when I was going over a speed bump with the wife and baby in the back seat.

That doesn't sound normal. I've never heard mine bottom out no matter how heavy its loaded.

Regarding the rear wandering when the road has grooves and uneven surfaces (I call it 'Tramlining') - I noticed that as the tire tread wears down it seemed to get worse. After swapping a new set of Michelins onto the car that tramlining has all but gone away. Maybe the case for you?

After I replaced only the rear struts on my avalon, the car never sags with a full car of people.
The 07 doesn't sag either.

AVA1, maybe the struts went bad already? Did you try the bounce test?

Apples to oranges. A GS is going to have a firmer suspension/ride than an Avalon.

How many miles are on your car? What are the road conditions like in your area? It could very well be that they are worn out, but expect to see it sag somewhat even if it was brand new.

Absolutely, but the point that I was making is that my GS was two years older than the Avalon. I'm just wondering if its the shocks worn out, or if it could be the springs are fatigued.

My friend has 190k on his '01 on his GS when it his dad traded it in for a Kia Forte. Original suspension was still good. That car road like a cloud even on 17" and bald tires.

KYB Excel-G but this was on my 99. On the 3rd gen its probably more complicated with reclining back seats and one piece rear deck.

Just push down and if it returns to the original position without any more bounces its still good. IF they were bad a road test over dips with excessive bounces from the struts will tell you they're bad.
