How To Change Carraige Bushings On 97 Dodge Intrepid

Download Article

Dodge Intrepid, built on the "Chrysler LH platform", had two generations: the first from 1993 through 1997 and the second from 1998 through 2004 which all have three engine mounts from the subframe (engine "cradle"/or undercarriage) to the engine and transmission. 4 bushings concord the subframe/cradle to the uni-body chassis. Bad mounts or bushings cause stress, premature vesture and damage of vital engine and transmission parts.

The two engine mounts and the transmission mount – also called insulators – on the Intrepid are fabricated of rubber (some may be "gel filled"), and a steel skeleton of embedded studs plus mounting bolts and nuts. With time, the rubber cracks, breaks-up, gets compacted, misshaped, and the mount can carve up or go fragmented. This decay causes more and more cluttered engine movement -- milk shake, wobble, clattering, vibrating, noise, bumping about -- must be fixed. Here's your ticket to save several hundreds of dollars.

1

Choose a level, concrete surface (strong 3/4 inch plywood can make softer surfaces or the ground workable). Set the parking gear and the brake. Block the wheels. Raise the front of the Intrepid with a jack(s) and support the auto with jack stands. Remove the splash guards nether each fender to reveal access to the mounts.
2

Place a total width slice of ii by half dozen, or 2x8 inch forest between a jack and the engine oil pan -- but non extending under the subframe. Raise the jack only until information technology simply begins raising the engine a very little, to mainly back up the engine, but not to raise the vehicle at all.

three

Loosen, but practice not remove the upper basics that connect the mountain to the upper mounting-bracket using a ratchet and socket. (If your mounts accept a estrus shield between the mount and engine, remove the nut or commodities from the subclass belongings the heatshield, using your ratchet and socket. Remove the heatshield.) Keeping the nuts loosely screwed on to just a few commodities threads, on the bolts, keeps the mounts aligned until both are loosened -- retained to this aforementioned degree, held on loosely, on each side of the engine.
four

Loosen the lower nuts: Only, do non remove them from the commodities attaching them to subframe, through holes in the subframe, using your ratchet, an extension and a socket, for both mounts.
five

The manual mountain: Ready to remove the tertiary mountain much in the same manner every bit the engine mounts (of a different pattern) at the rear of the transmission This mount may need to exist replaced for backward and forrad stability.

Advertizement

1

Remove the mount nuts and supersede just one mount at a time: Raising the engine far enough with the jack to get either i of the mounts off, then replace it as follows.
ii

Slide the studs on the lesser of the new mountain into the holes in the subframe -- and lower the jack a trivial to seat the engine mounting bracket downwardly lightly onto the stud(southward) on the acme of the mountain, maintaining alignment, then not binding, past tightening nuts and bolts little by lilliputian.
3

Install the lower nuts and "finger tighten" at the subframe, loosely equally before, merely by a few threads, to retain the engine positioning.
4
Install the upper nuts and "finger tighten", at the engine bracket, as well.
- Install the heatshield and its retaining bolts, if your vehicle is then equipped (on the 3.5-liter engine, for instance).
5

Install the transmission mountain by much the aforementioned techniques every bit the engine mounts.
6

At present, lower the engine a petty. Snug the nuts and bolts on all both mounts, at beginning just "finger tight". Then snug them all a little.
vii

Finally, torque all the mountain attaching nuts and bolts to the manufacturers recommended number of foot-pounds with a torque wrench and a socket. The large nuts and bolts might be torqued to about 45 to 50 pes (xiii.seven to fifteen.2 g) pounds. The smaller bolts on the manual mount are torqued less, possibly to near 20 to 30 foot (6.1 to 9.1 m) pounds.
eight

Remove the jack from nether the oil pan. Raise the front of the vehicle plenty to remove your jack stands or blocks and such, and lower the Intrepid to the ground.

Subframe bushings: Some other four rubber mountings are the iv subframe bushings, basically between the vehicle and the subframe and sandwiched by mounting washers and secured past bolts or studs and nuts.
The first generation, original platform, Chrysler LH platform, was based on the Fiat designed Hawkeye Premier (when Fiat owned American Motors).
The Intrepid platform (basic blueprint and structure) was the same as the Eagle Vision, and three other Chrysler models: the LHS (the successor to the New Yorker), Concorde, and New Yorker powered by a base of operations 2.7-liter, 3.3-liter or optional three.5-liter V-6.
