I'm keepin my ZJ drama to myself. I left the ZJ with a shop near mine after GF installed rear calipers in Jacksonville and I couldn't bleed them out down here. Turns out the calipers were installed upside down after hours of them trying to bleed them. This thing vibrates when the brakes are applied and continues to do so at a stop like the ABS motor it cycling them. I tried putting it in that funny " 4wd part time position" on pavement and it made horrible banging noises. I thought no prob, it sat for a year. Minutes later, that same horrible noise. Any ideas?

I should of said pulsation throughout the entire vehicle not a vibration. No they didn't use a scan tool, it's got plenty of pedal and feels fine getting on the binders until around 10mph and stopped it starts the rythymic pulsation sensation. Maybe I should install a disco ball and strobe lights.

I just found out they didn't replace the rotors when they replaced both seized calipers out back, though I don't see how this would cause the pulsation while at a stop.

Since they didn't replace the rotors while replacing the calipers?

After some reseach it seems this has the viscous coupled NP249 transfer case. I guess it has friction discs like a posi and probably requires the right friction modifier to prevent "posi chatter".The interweb tells me it takes Type7176 fluid Mopar ATF3, which has beed superceded to Mopar ATF4. I'm thinking I should get factory recommended transfer case fluid from a dealership for a couple bucks more, pack the slip yoke with grease on the front shaft (if it has one), and retry it in full time 4wd.

Great, I'll pull the fuse the next opportunity I get.

Hey morning! Do you have a charter captain that makes all sorts of noise loading and getting his boated started every morning at 5:30 AM too? Ah the smell of diesel smoke intertwined with Folgers is magical.
