Front axle will not engage- not the same ole post
Hey there- am new to the forum- just joined as I have a major repair appointment at 4wheeldrive in the morning- need some quick advice... Am not so new to Jeeps- I counted and I believe this is #9 or 10.
It's a 92 YJ. Front axle will not engage- UNLESS the axle is jacked up (no pressure on tires)--- which brings me to my next point- both tires are angled slightly inward at the top.
I just obtained this YJ (4 FREE) a few weeks ago- tires were tilted when obtained and before all my upgrades.....
So, no engage under pressure, tires tilted. Vaccuum acuator works fine- it has vaccuum and suction... but here's where it gets interesting--- the little coupler/slider/round thing that goes from the outter axle piece over inward when actuated.... well, it wont go.... unless no pressure on tires- then it will barely sqeak over to the inside and engage both axle pieces. I noticed a slight lack of a straight line between those two axles/pieces (inner shaft and shorter outer) they are not lined up perfectly straight... I suspect this is why my wheels tilt and what's binding to keep the front from engaging....
Axle shafts or housing or bearings/races/etc? There is no wheel movement when wiggled by hand, but I do hear/feel some clunkage from the front off-road over bumps- as if something is loose.....
But suspension/steering is not loose. U-joints 'look' fine.....
It's headed in tomorrow morning for gearing--- more input needed here- 456 or 488--- i'm running a 2.5L on 33s with new Rubicon Expresss HD 4.5" lift.... for future I can obtain a 6 cyl and when this 2.5 goes south i will upgrade but dont want to get stuck with wrong gearing then. I'm sure the 488 will do me some well needed good now, but will it be too much later with 6 cyl? Or should i even care at this point?!?!?
Anyhow, sorry for the long post, but am really hoping to have a grip on ideas about this front axle problem before they dig in on gearing tomorrow and surprise me with needing NEW EVERYTHING. My gear job tomorrow should include all gearing, bearings, etc--- they say they'll look at shafts and housing. I cannot find a local housing Dana 30-unbelievable I know. Suggestions greatly appreciated.
92 YJ: 2.5L/33s/4:88/lockers/all sorts of sh1t-- it's square and rolls over bumps! All WF members post your rides for use in Movies at: www.FilmProductionCars.com
