Front End Questions 2001 Chevy Suburban

Hoping to get some advice on a couple of issues I am having with my Suburban.

1) At low speed I hear a popping noise when I turn 45 degrees to left. Noise appears to be coming from under the hood on the left side.

2) Front end shimmy while accelerating at 50-55 mph. Car runs smooth until I reach 50 ish, while I am still accelerating a shimmy in the front end appears and continues until 55 - 60 mph or until acceleration is stopped.

Any thoughts would be appreciated.

Thanks!

Does it shake at 50 or 55 steady speed?
Is it 4 wheel drive?

It only shakes when accelerating up to and around 50-55, once you get above that it smooths out. It also stops shaking if you decelerate at 50-55.

I've had the tire balance checked, DT did correct a bit of out of balance, but it did not fix the problem.

Not 4WD, it's 2WD 1500 V8 5.3

Thanks for your response, any thoughts would be greatly appreciated.

as for that popping sound... it sounds like your left inner tie rod is gone.. best way to tell is a get a friend to put thier hand on it directly.. and then turn the wheel to left so it clunks... odds are he will feel it in his hand and have to replace.. they are cheap to replace.

On the second note I wouldve say tire balance is out... or if your tires are worn there is a chance the belt in the tire is seperating and causing an imbalance.

Ok thanks for the tip on the tie rod. I'm checking out some stuff online...doesn't look like too bad of a job to replace as long as I can find tool to get the inner rod out.

As for the imbalance, I had DT also rotate the tires recently with no change to the shimmy. If it were a bad tire wouldn't that have moved the vibration from front to back (if they rotated front to back)? Maybe I will rotate them front to back myself and see if that help id a bad tire.

Thanks again for the response.

Popping noise

Probably the poping noise is coming from the link that connects your steering column to the steering gear box under the hood (splinded Shaft) GM had a recall on it to lube it diffrently or replace it if lubing didn't solve the problem check with your dealer to see if this has ever been done.

No idea's other than tire balance on your shimmy problem so sorry no help there

check all the boots on the ball joints. if cracked or ripped, or in some extreem cases the center will be entirely worn away. this lets in the water inturn removing the grease. i would not put on a new boot and fill with grease. i would replace the whole ball joint.

AS for the shimmy, you need to get an allignment, from what you are describing it sounds like you have too much tow out.

goodluck
