I have an 89 k5 with a 3" suspension lift and 33" tires. It still has the factory tie-rods/ball joints many of which have busted grease bladders. It's a little worn out and loose - big deal right - it's a 4x4 that sees very little highway use. I did have a busted front leaf but had that replaced months ago. I still grease the zerts when I change the oil just for good measure. My problem is that when I'm traveling at any type of speed and begin turning left the truck will often track left suddenly as if someone jerked the steering wheel. It doesn't do this turning right and this problem just started in the last 6 months? Yesterday I was pulling a slight left turn on the freeway and about shot into the wall! It scared the (*^*(&% out of me! Driving slower around in the city around 90degree corners and through tight parking lots the steering seems just fine and responsive? Put this rig on the freeway and it feels like all my lug nuts are loose. It's an old rig but it's only an 89! I've driven 70's models that are tighter than this. Replacing all of the balljoints and tierods is an expensive laborious project! I have noticed that when I'm traveling straight my steering wheel is turned a bit to the left and it used to sit straight. A longer steering arm fixed most of my bump-steer. How do I tell if it's time for a new steering stabilizer and or shocks?
