Pontiac trans sport stötdämpare bak!

1
Hej!

Ny på forumet här. Har just investerat i en Pontiac trans sport -93 V6 automat.
Skall byta stötdämpare bak på den och undrar lite hur detta funkar, det är nån typ av nivåreglering på den. Går detta med luft eller olja? Det går några smala slangar till dämparna, sen sitter det en liten kompressor längst bak på vänster sida, hör detta till dämparna eller nåt annat? Nåt särskilt att tänka på vid bytet, förutom det "vanliga" vid stötdämparbyte?

Detta är mitt första åk av märket Pontiac, hoppas inte det blir den sista, man åker ju gott i denna. (fast just nu gungar det ganska gott i bakändan) :wink: Lite för gott inför en förestående besiktning antar jag.

Kanske inte är till hjälp, men här finns en repguide på Autozone:

Funkar inte länken riktigt, så välj år/märke/modell sedan Suspension.

Klistrade även in infon, men bilderna kom ej med här:

TESTING


The purpose of the shock absorber is simply to limit the motion of the spring during compression and rebound cycles. If the vehicle is not equipped with these motion dampers, the up and down motion would multiply until the vehicle was alternately trying to leap off the ground and to pound itself into the pavement.

Contrary to popular rumor, the shocks do not affect the ride height of the vehicle. This is controlled by other suspension components such as springs and tires. Worn shock absorbers can affect handling; if the front of the vehicle is rising or falling excessively, the "footprint" of the tires changes on the pavement and steering is affected.

One of the simplest tests of shock absorbers is to simply push down on one corner of an unladen vehicle and release it. Observe the motion of the body as it is released. In most cases, it will come up beyond it original rest position, dip back below it and settle quickly to rest. This shows that the damper is controlling the spring action. Any tendency to excessive pitch (up-and-down) motion or failure to return to rest within 2-3 cycles is a sign of poor function within the shock absorber. Oil-filled shocks may have a light film of oil around the seal, resulting from normal breathing and air exchange. This should NOT be taken as a sign of failure, but any sign of thick or running oil definitely indicates failure. Gas filled shocks may also show some film at the shaft; if the gas has leaked out, the shock will have almost no resistance to motion.

See Figure 1

While each shock absorber can be replaced individually, it is recommended that they be changed as a pair (both front or both rear) to maintain equal response on both sides of the vehicle. Chances are quite good that if one has failed, its mate is weak also.

REMOVAL AND INSTALLATION


Open the lift gate, remove the trim cover and remove the upper shock attaching nut.
See Figures 2 through 6


Fig. 2: The trim cover is held in place by snaps and can be removed by carefully lifting it off
Fig. 3: The cover can be completely removed to get it out of the way
Fig. 4: There is a rubber bumper cover over the top mount of the shock
Fig. 5: Pull the rubber cover off for access to the shock upper retaining nut
Fig. 6: Use a deep socket with an extension to remove the shock upper mounting nut

Support the rear axle and safely raise the vehicle.
See Figure 7


Fig. 7: This is the top of the shock as viewed inside the wheel housing

If equipped with electronic level control, disconnect the air hose.
Remove the lower attaching bolt and nut and remove the shock.
See Figures 8 through 13

Fig. 11: ... then lower the shock and remove it from the vehicle. Removing the upper mounting brace with the shock, to inspect for wear

To install:


Position the shock at the lower attachment, feed the bolt through the holes, and loosely install the nut,
If equipped with electronic level control, connect the air hose.
Lower the vehicle enough to guide the upper stud through the body opening and install the nut loosely.
Tighten the lower nut to 44 ft. lbs. (59 Nm).
Lower the vehicle the rest of the way, then tighten the upper nut to 16 ft. lbs. (22 Nm).
Install the rubber bumper and trim cover.

Tack, lite hjälpte det nog, men min engelska är ju inte den bästa :oops:
Som jag förstår så är det alltså luft som går till dämparna, eller??? Har inte tittat så mycket på detta ännu, men ska göra det bara det blir lite varmare ute, idag har det varit - 24 grader här, har man inget garage då så blir man inte så sugen på att hålla på med skruvande :)

Om nån vet lite mera om detta så skriv gärna, allt är välkommet, ex.vis den lilla kompressorn som sitter där, är den till dämparna eller nåt annat, har ingen instruktionsbok till den.

Tack på förhand!

"If equipped with electronic level control, disconnect the air hose"

Ja, det ska vara luftdämpare enl. Autozone:s manual.
