hey guys, i realize this is a non-tech forum, but i felt it didn't belong in XJ and MJ tech discussion. this is going to be long winded, but i would truly appreciate it if you would stick it out until the end.
my sister has an 07 jeep compass. FWD, 2.4L. 59K miles. a few days ago she called me saying she heard a loud tapping/clicking noise coming from the engine bay, that got faster as she accelerated. just from hearing the sound over the phone, i assumed it was an exhaust leak. she called me back a few minutes later and said her RPMs were high, but there was no power. once again, possibly a major exhaust leak.
went to her house the next day, and started it up. listened with hood open, didn't hear a thing. as soon as i started driving it around, i could hear the click. sounded like it was coming from front left/ front left-middle of engine bay. so obviously, exhaust leak was out since it only happened while moving. as i was coming to a stop, it started bucking like there was still forward motion but it was "catching" (for lack of a better word). i assumed it was probably a CV axle issue.
jacked it up, yanked off the tires, started snooping around underneath. driver's CV axle would rotate about 1/8"-1/4" either way, passenger side axle was fine. none of the CV boots were ripped or torn, no grease leaking out, no signs of wear. had my sister start it up and put it in drive while i was underneath. driver's side CV axle was wobbling like a warped pool cue running across a table. not bad but noticeable. noise was coming from the transaxle area. decided to yank the shaft out. got it out, and listen to me carefully....gear oil (i.e. GL5) came out the axleshaft hole. now i've gotten differing opinions on this part, but the general consensus is that newer cars have a seal seperating the transaxle and transmission. I'd say 95% of the work i've done on cars has been RWD so this is new territory to me.
anyways, pulled the boots off the CV axle and i don't SEE anything catching my eye, but once again, CV axles are not my "forte" so i may be missing something. I will say that the slip-portion of the shaft (joint closest to tranny shaft where the joint slips inside, I'm assuming to compensate for turning radius) will NOT come out of the housing. It's 50/50 split when talking to buddies about whether or not it is suppose to come out or not.
Here is the bottom line. I need to know for SURE whether it is the CV axle or the tranny. My sister is 31 with a 18 month olf daughter, and was unemployed for 10 months before taking a VERY low paying job, as a 31 year old with a bachelor's degree. I'm taking a personal day off work tomorrow to help them all day with this issue, and hopefully we can get it panned out. Life is hard for them right now and the last thing they need is to be buying a tranny or having it rebuilt, or even jsut throwing parts at it and hoping something sticks. ANY suggestions or advice whatsoever would be greatly appreciated, and thanks for taking the time to read this.
