I have replaced all four with MONROE shock absorbers, MOOG tie rods and ball joints after 100K miles but don't really see a big difference.
Please advise what else can HELP smooth the ride.
THANKS

 

What kind of truck? And was there a sudden change that was noticed? We need more info. Need a wheel balance perhaps?

 

V6 4.2L FWD with a wheel alignment after PARTS replacement but very small improvement while driving. Tires Not in very good conditions but last time a wheel balance was done was last year.

 

From my experience you can replace all the suspension components you want, but if you have a worn out set of tires it will still ride like a flintstone car. If you get a decent set of tires, they don't even have to be new, but have at least 50% tread and I am pretty sure that you will be able to tell the difference. Not only that, you will actually take advantage of the new suspension parts that you installed.

 

I for one don't get it??? Even with crappy tires, which is a significant part of the puzzle I agree, how on earth can you change all that and not notice a difference? That's crazy.
Get tires and good luck.

 

Also if you have lt series tires you can switch to a p series.
