I own a 2004 Santa Fe 4WD LX, 3.5L V6 with 5-spd Automatic and "SHIFTRONIC" Function. The vehicle has 135K miles of wonderful service to the family including pulling a 12ft pop-up camper on some great outings.
Within the last several months, a "jerk" started occurring when pulling away from a stop and when passing 20mph. The severity and frequency of the "jerk" varies from none to bad. The bad occurances happen more when going up hill.
A recent diagnostic at the local dealership resulted in the replacement of the purge valve because of diagnostic code 133299. After replacement of the purge valve, the "jerk" still exists, but not as bad as prior to the purge valve replacement. When questioned about this, the maintenance team at the dealer indicated that "jerk" might be a failing viscous coupler. In reading this forum, I found information stating that this model should have a magnetic coupling mechanism rather than a viscous coupler.
What could be causing the "jerk"? I will not tow the camper again until I know. Also, where can I get definitive information on the rear differential?
