Quest shakes at high speeds

I have a 2002 Nissan Quest with 115,000 miles one it.

The car shakes at around 60-80 mph then seems to go away.

I have a got a 4 wheel balance and tire rotation, recently.

The vibration didn't seen to start until after the brakes were replaced and the rotors were turned by nissan.

Should I just replace the rotors? What else could cause it?

Thanks

I took the quest back to the place where I had the tires the balanced at and had them redo like you said. They also checked the rims and gave it a front end alighnment. Now it stills shakes at high speeds?

They also said everything looks good as far as the tie rods, cb boots, ect.

Thx,

I had someone else drive the van and asked for his opinion.

He had me turn the wheel while he felt the wheel and he felt a "pop", then I felt the wheel while he turned and I felt a pop. He said the "pop" comes from the tie-rods and that was causing the problem.

What do you think?

Well I tried changed my tie rods last night, and got the car realighned again. Same shaking.

What do you suggest next?

Your right, sometimes is best start from the begining.

Things that have done, since shaking.

1) Replaced motor mount

2) Brakes pads replaced machined rotors from nissan

3) Retreaded and retighted the motor mounts.

4) 4 Wheel Balance, Front end alighnment, rotate tires

5) had them rebalance and recheck for a bent rim

6) replaced tie rods

6) another alignment

I didn't think about an alignment on the motor mount, when they replaced the motor mount earlier they could of throw it or the transmisson out of alignment? It could be just the motor or transmisson shaking.

Also the cat still pulls to the right even after the alignment?

But, I took your advice and looked at it. It might be me but it looked like when the left tire was straight the right looked a wee bit going to the right.

And the poping not there. But I could bearly tell anyway.

I'm thinking of taking it to nissan and asking them to to recheck ALL of the alignments motor mounts, wheels, everything.

Wouldn't a axle shaft show up at low speeds, also?

What do you think?

Thx

PS the tires are Goodyear Regatta 2, about a year old.

FREAKING GOODYEAR TIRES, MAN!

FREAKING GOODYEAR TIRES.

I HAD goodyear tires on the van, that where less than 6 months old, that looked new. It had a lot of thread left on them.

I took it to a an out of town dealership and asked them, and they said that the tires that Goodyear makes don't work on the Nissan Quest and Mercury Villagers.

(sigh)

Well, hopefully this post will help someone else out.

Thx for all your help.
