Question about 2003 Buick Rendezvous

1 Answer

Super stiff left rear suspension

My left rear corner started rumbling badly over tiny bumps - just in a parking lot. Two weeks later, the suspension on that corner is super stiff and any little bump at any speed it like being hit with a huge hammer. If I push down on that corner, it almost doesn't move at all. Thanks!

    OK, I have no idea why my issue appeared under 2003 Buick Rendezvouz. It's a 2001 Lexus es300 and that's where I was when I posted this. But, for the record, the rumble is akin to guy nextdoor using a tap hammer on a nail to put a picture on the wall. And I don't hit the gas hard in parking lots. I'm 48 and I'm over that behavior! It happens whether or not I'm on the gas, at all. And the bumpiness, especially when I'm up to speed, is absolutely bone-jarring.

If there is no noise when driving the car over a flat bump-free surface, it tends to suggest that the problem may well lie in the shock absorber or spring .. or .. as someone else has pointed out .. the bushes. A worn rubber bush permits metal to etal contact - the tapping noise .. and can also cause vibration.

Pushing down on the corner of your car should feel stiff as you are pushing against the shock absorber. If the spring is broken your car well make a heavy 'crashing noise' over each bump. Though any rubberised bush that is worn can also cause the same sound when driven over a bump.

If the car makes that tapping noise even when driven over an even surface it cold point to bearing troubles. However, as you say that it is bone jarring when up to speed suggests the problem lies in either a loose wheel nut, an out of balance or damaged wheel rim or worn rubber bush - or something worn that allows metal to metal contact.

The easiest solution - and the cheapest - is to take your car to a workshop. They will tell you within minutes what the problem is. If you try and replace parts yourself to cure the problem .. well .. usually we replace the wrong part and end up paying more for parts before we find the problem. The other point to bear in mind is that it isn't always easy to identify something like a worn rubber bush when the car is standing on the ground. It's easier when it has it has the weight lifted from its wheels - on a hoist.

Get your car to a workshop and let them identify the fault. You can change the worn parts yourself

These are side products of the all wheel drive system, incombo with the locking rear dfferentials.

You'll find the auto-lockers will tend to do that following a tight turn, particularly when you're doing it quickly.

The thud is similar in nature; it's just the All wheel system trying to figure out where to put the power.

SOURCE: Front driver side suspension knock over bumps

See if you can bounce car and replicate the noise. If you can, you should be able to find it, and put your hand on it. Stabilizer bushing are a place to look, both at the lower a arm and on the frame. If you narrow it down to the strut, it will need to be replaced. The front trans mount also goes bad, try putting it in drive with your foot on the brake and give it some gas and see if the engine moves an excessive amount.

Your Buick LeSabre may have air shocks on the rear. Check the shocks for leakage or stains from previous leaking. If the shocks are leaking you'll need to replace the set. Don't replace only one shock-replace them both.

FRONT END SUSPENSION Squeak


It is hard to tell with out more detail as to what makes it squeak. Does it squeak when you hit a bump, or while the vehicle is in motion? To test your struts simply push down on each front corner (above or next to headlight)as to rock the vehicle up and down. Pick a solid part as to not dent it. This is a good way to test your struts. If it goes up in a stiff motion(not rocking) its probably good. If it goes up and down easily and has a lot of play then your struts might need changes. The squeak could also be sway bar bushings as well. If it only squeaks when your in motion it could be your cv axle. If you are still in need please post more detail as to better diagnose the issue.

What's your problem?rumbling sound coming from the rear rightside every time I go over a bump or unsmooth tarmac


Look at the rear suspension. I think it is one leaf spring upside down over top of the axel. At the ends they are grinding in there seats. Jack the vehicle up by the body clean out the spring seats and oil them a little its just showing its age.

Left rear is sqeaking


Several possibilities, You could have worn out brake pads or a brake pad scratcher telling you it is time. You could have bad wheel bearings. If you back into parking spaces till you bump the curb, you could have broken or bent suspension bushings. Could just be one dry shock absorber. Could be an automatic brake adjuster that is set too tight causing brake pad glazing/squeaking. If it happens when you bounce it is suspension. If it happens when you roll its Brake/bearing.

Truck rumbles going down the road


These trucks are bad about that at around this millage. The front and rear have stabilizer bars that attach to the frame. These have large rubber bushings that wear out and cause this sound. replace the bushings and see if that doesn't help. Good luck.

I hit a bump on the right front side and it makes a roaring type noise and shimmies a bit .. can feel it under my left foot. also at times it will make that soud when i make a right hand turn... it is ...


Sounds like your left front wheel bearing is going bad. When you make a right turn, or compress the right front suspension over a bump, it forces the car to roll to the left. This loads the suspension on the left side, which will exaggerate a wheel bearing problem. Are you hearing the noise at all when travelling on the highway in a straight line? If so, it'd be either a grinding sound or a hollow humming noise. If you aren't, it may be that the bearing is just starting to go bad.

A quick test to see if the bearing is bad is to jack the car up at that corner, grab the wheel at the top and bottom, and shake it hard - if there is any movement or looseness, your bearing is shot. If there is none, it doesn't mean the bearing is fine, but it could be that it's just starting to go bad (which would be why you only hear it in turns and bumps, but not straight-line yet).
