My 97 Tahoe with 221,000 miles on it recently had the front calipers replaced, new shocks up front, upper and lower ball joints replaced, new rear brake shoes installed, differential rebuilt, and a front end alignment, all but the shocks done at a GMC dealership. Upon very firm breaking the vehicle pulls to the right, kind of nose first. GMC dealer says brakes are fine all around but the problem is the drivers side leaf spring is shot and if I replace one I should replace both. Is this a logical diagnosis, that a weak drivers side leaf spring could be the cause for the truck puling right upon firm braking? Thanks for your opinions. I am also getting close to my limit of how much $$$ I am continuing to put into my Tahoe, while maintaining some reasonable amount of sleep. I am the original owner. I have 100% of the repair records on the vehicle, over 23 years worth. I may soon hit my limit and offer it up for adoption to another Tahoe fanatic. All systems are running well, including A/C. If you want to be on that short list let me know.
