AFTER GREASING BOTH UPPER BALL JOINTS ON 2006 GMC 2500--GREASE SPITS BACK OUT--INITIAL LOOKED TO BE OLD GREASE, I AFTER A COUPLE DAYS WENT TO REGREASE AND NOW THE NEW GREASE SHOOTS BACK OUT.

Most vehicles have long been manufactured without grease points using either rubber bushes and lubricated for life joints and far from older vehicles having around 30 grease points, those that retained a few grease points confined them to the propeller shaft and the front ball joints.

Sometimes in an effort to prevent over-greasing, the manufacturer would fit a blanking plug that would need to be removed annually and temporarily replaced by a suitable grease point and given just one stroke of a manual greasegun.

Many things can squeak and a strong assistant bouncing the vehicle while you listen at various points with a sonascope is an invaluable method to trace the source.

Rubber bushes often squeak as they age but ball joints and track rod ends can make a terrific racket when the grease escapes - usually evident by a damaged rubber cover...

I am not familiar with the model but many vehicles have a variable number of grease points - not all fitted with grease gun points. Some ball joints, prop shaft U/Js and other suspension joints can be damaged by too much greasing and so blanking plugs are fitted and a grease gun adaptor fitted temporarily during certain maintenance services for one or two strokes of the grease gun and then the blanking plug refitted.

Enthusiastic owners sometimes fit their own grease gun adaptors and throw away the blanking plugs...

Rudy, From the factory, the Buick LaCrosse probably had no grease fittings on it. Over time parts may have been changed, the new parts may or may not of had grease fittings. Grease fittings for steering could be found on lower ball joints and outer tie rod ends if they had been replaced. Check the attached links,instruction and guides, Good luck

Did you lube the sway bar mounting pads? If these are urethane, they will squeak like crazy without silicone lube.

Here's a link to the lower ball joint,it tells you about a fitting to be greased,as you see the ball joint has a hole at threads where greasing fitting will be.It will be best to jack up and remove tire to grease,look for other grease fittings,wipe up excess grease.Also check ball joint for wear,may need replacing.

Flush the power steering fluid, and add some lubgard power steering additive, from auto parts store

LUBGARD brand only, or the one from a ford or lincoln parts counter.
( regular lubgard p/s--not for Honda Only )

You can grease if you have fittings,but that is not your squeaking noise.

There should be some on the front end steering linkage, and some on the drive shaft front and rear, there is none on the rear end.

The ball joints should be changed not greesed. It's really not to difficult and you can get them for around $27.00.
