Higun I would think they would be designed to last a few thousand miles past the warranty, whatever that is. I know I drive a one ton dodge truck and it eats front end parts. Not a cheap fix either. Dan
I made a ton of money doing ball joints, especially on Ford trucks and the Taurus. I never did understand how they lasted forever on Japanese vehicles, but wore out constantly on American made cars and trucks. There were times when vehicles would have less than 36,000 miles and they would be completely wiped out. Unbelievable.
I don't know how good your 07 suburban has been but I purchased one brand new for my wife and it was a pile of sh!t from the get go. Needless to say it was traded on a brand spanking new Mercedes Benz.
Get after market ball joints, non geaseable they generally last longer because little chance for water and dirt to get in. Grease zerks are where they get in from. If you get greasable ones, lube them offen!
After market ones are generally better. I had a set in a Ford 4x4 that were NAPA's best life tiime ones. LASTED one week!!
I bought the “Burb” new in 2007. I have it in for grease, oil & filter every 3000 - 3500 miles at the original dealer. That can be documented.
I had an accident at about 55,000 miles and was told that the upper ball joints on both sides needed replacement as a result. The ball joints were replaced and the insurance company covered the expense.
Last week I went in for my usual service and the technician recommended replacing the upper ball joints on the right side. I’m currently at 110,000 miles. It seemed unlikely to me that ball joints should last only 55,000 miles.
99.9% of my driving is done on relatively smooth paved roads.
The vehicle has been great in all respects. I just don’t want to fall victim to an unnecessary repair.
I think I’ll get a second opinion from another shop.
Agreed strongly with Miketmx. Go with MOOG performance parts. Very good price on very good parts. Have used them in two different dirt track race cars and they performed flawlessly. You can't abuse them much more than we did on the track. Bret
