2002 Jeep Liberty Front Drive Shaft, 2005 Jeep Grand Cherokee Front Differential Mount Fix – We’re relatively specific that when Chrysler’s design group axed the WJ’s typical strong front axle for a totally independent setup in the ’05 Grand WK, exactly what they really did not expect was the front end coming to be totally independent. See, we’ve just recently included an ’05 Grand Cherokee Limited to the fleet– as well as unbeknownst to us after acquisition– its front differential had actually been functioning vigilantly to parting means with its host Jeep. Its ways of getaway? 3 steel-sleeved rubber bushings act as the single link factors in between differential and also subframe, as well as most of them were shrieking uncle after 8 years of arm fumbling with the Hemi under the hood.
We’re not totally certain why the resulting clunking and also recurring driveline resonances went totally undetected throughout our first examination drive– however if they had– Jeep-buying procedure typically determines that entirely roached wear things be placed to great usage as take advantage of versus vendor’s asking rate. Oh well. Made use of is utilized besides, and also we’re thinking that the life-span of these bushings was quickly sped up under our possession many thanks to unjustified, teenager-like use the go-pedal. We just weren’t totally at fault, nonetheless. A general Interweb search informed us we just weren’t alone, which early differential-mount failing (our Jeep has much less compared to 90K on the clock) was quite typical in both WKs as well as the Commander XKs that share the exact same system.

Because there appeared to be no scarcity of concerns on the internet focusing on a strong master plan for those changing these bushings in the house, we’re going to provide you a play-by-play below. We’ll reveal you exactly how we took on the task and also with any luck make it draw a little much less for you. Considering that our regional components shop really did not reveal a listing, we sourced brand-new OEM-bushings from our neighborhood Jeep dealer to the song of around 200 dollars. 2 from the 3 bushings are pushed right into big, cast-in eyelets– one over the differential pinion (one of the most worn-down of the number) as well as the various other over the outcome for the right-hand Curriculum Vitae shaft.
Certainly, the just one from the lot that was screw in as well as conveniently changed– the front-support bushing– was the just one that was A-OK. That’s to claim how much time that a person would certainly last, however, so we changed it forever procedure. We tackled this work with the advantage of a car lift as well as our good friends at Importech in Conway, New Hampshire, to assist record the tale, yet if you have a standard tool-set as well as a suitable concept of how you can use it, you’ll have success at residence with a flooring jack as well as a set of purposefully put jack stands.
The clunking noise that initially suggested that an issue required fixin’ was most recognizable when changing from Park to Reverse or Reverse to Drive. A glimpse below– with a friend dispiriting the brake as well as rowing the equipments– created a fast medical diagnosis. Whenever the torque tons altered instructions, the differential ends of the Curriculum Vitae shafts would certainly leap up and down over an inch in either instructions.
With both knuckles and also show off settings up still affixed to the reduced control arms, we drew the top of the knuckles out and also away from the lorry sufficient so the Curriculum Vitae shafts would certainly draw without the real estate. Currently you’re all set to unlock the driveshaft from the differential, pull the duct tube, reverse the electric link up leading, and also zip-out the screws that go through the 3 install bushings (arrowheads).
After standing out the front wheels off and also establishing them apart, we accessed to the front driveline by eliminating the huge skidplate bolted to the subframe. You should completely eliminate the back 2 screws, however simply loosen up the front 2 adequate to glide the skidplate onward in its slotted networks and also allow the washing machines travel through the openings.
You could see where the rubber of the pinion assistance bushing tore and also started parting means with the steel covering. With a lengthy strike via the facility sleeve for take advantage of, we can modify the sleeve side-to-side to the factor where it got in touch with the external steel covering of the bushing. Bad. If we’re able to control the bushing this much with a strike, you could picture the hurtin’ that 375 lb-ft of engine torque placed on it.
There’s no should totally dismantle your front suspension, unlock the axles from the unitbearings, or touch the brake equipment to tackle this task. By just unlocking the top control arms and also external tie-rod finishes from the knuckles as well as the persuade bar end web links, we released points up sufficient to stand out the Curriculum Vitae shafts from the differential.
The quickest as well as most efficient methods of eliminating your differential of its invested bushings is with an air hammer putting on a carve little bit. We utilized the air hammer to flex the lip of the steel covering internal in the direction of the facility of the bushing and after that pressed the whole bushing out to the non-lip side. One bushing is pushed right into a more-damage-prone light weight aluminum real estate, so make sure to take your Machine Gun Kelly hat off when you blow up that out.
It took around 5 mins each bushing to jackhammer them without the differential– certainly not rather, however reliable. The exact same objective could be achieved with a hammer, carve, and also significant steel-punch, yet you’ll possibly want that you had actually obtained your friend’s air hammer when via. The front assistance bushing (not imagined) merely unlocks from its cast-in install on the finned front differential cover.
Given that we really did not have any type of good luck locating bushings at any one of the regional components shops, as well as there really did not appear to be anything offered as an aftermarket upgrade, we were stuck sourcing O.E.M. bushings from the regional Jeep car dealership. Both pressed-in bushings are created to bend in a specific instructions and also have to be set up in the very same positioning as the ones that appeared– with the level of the facility sleeve encountering up.
Your finest master plan for setting up the brand-new pressed-in bushings calls for a round joint press. If you do not have one, the majority of components shops lease them, or you could select an el-cheapo Harbor Freight device that we’ve in fact had respectable luck with. As soon as all the bushings remain in, you’re prepared to raise the differential back right into area and also switch whatever up similarly it was undone.
