97XJ, 2" budget boost, new 31x10.5's, SYE and tom woods shaft on rear, tom woods shaft on front, all (all 8) U-joints replaced about 6 months (15,000 miles) ago. NP242, AW4, 4.0L engine. D30 in the front, stock gears. Crappy gas mileage (18 max).
Over the weekend I used 4L to crawl up a washed out road, moderate incline for FL. Somewhere in the front drive line was a loud popping noise, speed dependent. Almost sounded like an axle U-joint.
In 2H no noise. In 4H part time on dirt, noise when I accelerate, in 4H full time on pavement also noise when accelerating. Haven't tried at speed, too loud/don't want to launch anything.
I looked at the suspect U-joint today, no rust, so a couple of questions:
1. what is the life expectance of an axle U-joint?
2. If it is an axle U-joint and I continue driving it (in 2WD) will it last a couple more weeks?
3. If it is an axle U-joint and it grenades while in 2WD, will it take the knuckle with it?
Thanks,
Mark
