When driving car swaying on the rear axle for lancia kappa 2.0
Last time we changed the 4 shock absorbers after that when we test drive on it the car swaying on the rear. we checked the wheel balanced of the tire but all ok. I tried to get technical data to check whether i have done wrong and where is the adjustment for the rear if in case we need to go for wheel alignment? because when i look underneath i found only a linkage bar only for adjustment for toe in only. There is anybody can give me a technical data and information regarding this matter. By the way car is lancia kappa 2.0 year 97,Thanks

Re: When driving car swaying on the rear axle for lancia...
Replace the rear sway bar links or the sway bar bushings. Either or will cause a sway in the rear. If it is one side of the rear is off set . Car going down the road at an angle. Align the back of it...then realign the front.

Don't drive it further than a local garage/technician or an experienced neighbour. Something maybe adrift in the axle/suspension area and could lead to a crash. Most likely its one or more rubber bushes in the suspension need changing. Check your shocks while you are down there.
the main problem is that someone is trying to drive it way too fast. narrow wheelbase and high center of gravity have spelled fatality many many times and nearly killed the Ford bronco II. it seems obvious to the casual observer but thousands of deaths and lawsuits resulted in recalls consisting of video tapes telling folks that you do not drive vehicles with narrow wheel bases and high centers of gravity very fast. The second problem is that the thing is nearly an antique. every part on that vehicle will fail from either time or use, or a combination. So 16 years of time and use have worn out every suspension and steering component. If you want to drive fast, get a low slung wide track unit. If you want it to drive like it is new, replace all the steering and suspension components and get a good 4 wheel alignment.
Could be a broken shock absorber, abroken sway bar link, or just worn rubber bushings on any of these parts. You will need to get under the vehicle and visually check all these points, both where they attach to the rear axle and to the frame.
Your rear axle is the part that runs between the two rear wheels. The shock absorbers and springs are always attached to it. On a rear wheel drive or four wheel drive vehicle there is a bulge in the center of the axle where the gears are located. On a front wheel drive car, the axle may just be a length of box steel. On a rear wheel or four wheel unit there are drive axles inside the housing that connect the gears to the wheels. On front wheel drive there is a spindle on each end with bearings and a flange to mount the wheel.
On 4-door sedan, remove the package tray and vent duct.
On hatchback, remove the speaker grilles.
Disconnect the brake line from the wheel cylinder.
CAUTION Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with the eyes and wash your hands thoroughly after handling brake fluid. If you do get brake fluid in your eyes, flush your eyes with clean, running water for 15 minutes. If eye irritation persists, or if you have taken brake fluid internally, IMMEDIATELY seek medical assistance.

The remainder of installation is the reverse of removal. Tighten each component to specifications.
On the 4-door sedan, remove the package tray and vent duct. On 1992-96 models, it will be necessary to remove the rear seat back.

If equipped with ABS, disconnect the Load Sensing Proportioning Valve (LSPV) spring from the lower arm.
Disconnect the stabilizer bar link from the shock absorber.
Support the rear axle and loosen the 2 bolts from the lower end of the shock absorber.
From inside the vehicle, unbolt the upper support.

Fig. 2: The upper shock absorber tower is retained by the center nut (circled) and three surrounding nuts
Lower the rear axle carrier and remove the two bolts.
Remove the shock absorber from the vehicle.
Install the shock absorber assembly onto the vehicle.
Connect the brake hose and the ABS speed sensor to the shock absorber.

Tighten the suspension support-to-shock absorber nut to 36 ft. lbs. (49 Nm) on 1988-91 vehicles. On 1992-96 models, tighten the stabilizer bar link to shock absorber retainers to 47 ft. lbs. (64 Nm).
Install the rear seat back, vent duct and the package tray as required.
The front[or rear] sway bars have links in them that are rubber mounted,it sounds like one of the sway bar links is broken,or one of the sway bar bushings is missing.Find the sway bar and have a close look at the mounts to see if the problem lies here.
