#5 of 8 blazer 2003 vibrations over 60 mph
Jul 06, 2009 (1:08 pm)
I need help. I have a 2003 blazer ZR2 that I bought with 83,000 miles on it. I have replaced ball joints and rotors and pads and bought new tires. does anyone have an idea of what the problem may be? The vibrations seems to consume the whole vehicle--coming from the front.
#6 of 8 Vibration @ 60+ MPH

Vibration at 60+ mph is typically due to tire imbalance, tire force variation or tire wheel assembly force variation. Base on the age of these vehicle, I assume the tires have been replaced. Tires that come from the factory have force variation specifications aftermarket tires do not have to meet these same specifications. Tire retailers service garages typically donít do the best job balancing tire wheel assemblies. Assemblies should be balanced for both static and dynamic balance not just static. Some retailers have balance equipment that can also measure assembly force variation and can minimize the assembly force variation by vectoring the assemblies. You might want to see if you can find a retailer that has the ability to perform this type of analysis.

I Feel your pain. I have a 2000 4x4 and I bought it when it had 18,000 miles. It now has 280,000 miles. I have had the same problem with ball joints and wheel bearing assemblys. I have since learned some things about these SUVs.
#1. They have built these with small truck parts on the front and that's why they eat ball joints and bearings
#2. The shocks need to be a heavier duty shock then what was originally installed on the vehical. Replace the shocks soon.
#3.Replace all your front end parts with "Moog"auto parts. They really make a difference and have a lifetime warranty if you ever have to replace one.
These Small trucks also have a part in the trans that is weak and has since been updated that may go on you,. Forgive me I forgot what the name of the part is!
Other problem is the fuel pump is on top of the gas tank and is hard to replace. Make sure you change the fuel filter often to avoid having to replace the pump too soon!!!
On the positive, The Vortex V6 in these run great and are powerful as you can see with how many miles I have on mine. Also the paint and body is great on these. Mine still looks new and I have had many deer bounce off the thing at night and barely have a dent.
I hope you have as good a luck as I have had with mine.
#8 of 8 2002 Blazer gas tanks and spare tire carriers

Does anyone know of a Chevy or aftermarket gas tank that is 20 gallons instead of the 15 gallon tanks that came with the gas guzzling vehicle?
How about an external spare tire carrier?
