Experiencing a shudder under load a 50-60 mph. It's like a momentary loss of power that pulses until I reduce speed or give it gas. Not sure if this is a tranny issue, driveline issue, or something else. It feels like it is in the front end almost like a tire is skipping or something like that.
Recently replaced the rear driveshaft for a bad slip yolk. The front drive shaft has new OEM u-joints about 20k miles ago and was recently lubed. I just did a rebuild on the front left steering knuckle as the seal had gone bad and grease and gear oil had mixed in knuckle and in the diff housing. RCV birfields and shafts. This is a supercharged engine. No noticeable tranny issues (except for typical reverse problem) with recent fluid change about 15-20k miles ago and new filter. 35" tires on OME kit with OME caster correction. Recent replacement of fuel pump with OEM denso pump.
Any ideas on what might be causing this problem? I am at a loss.
