How do you set rear end alignment on a 1988 nissan 200sx it is wearing out the inside of the tires there is an adjustment on one of the arms the bolts look like they slide up about 3/8 of a inch i can not find any info on this setting

Springs are sagging or suspension is bent. Could be worn bushings causing components to be out of position. Springs support the weight and the shocks dampen the bounce so he doesnt keep bouncing- if it does then you need shocks. The sagging indicates something else is wrong.

ABNORMAL REAR TYRE WEAR Ford Focus 2000-2004

"Ford Motor Company told dealers that they may need to replace the rear upper control arms on Ford Focus models. The models include: 2000 through 2004 Focus Sedan, Wagon, ZX3 and ZX5 series.

According to Ford, consumers have been experiencing more than normal wear to the inside of the rear tire(s). Should owners experience such a condition, then they should bring their vehicle in to a Ford or Lincoln Mercury dealership for a possible adjustment. Ford will check the rear camber and, if possible, make an adjustment. If an adjustment to the vehicle's rear camber is necessary beyond the negative end of specification, then the dealership will need to source replacement rear upper control arm(s)."

The Ford Motor Company parts service kit required for this replacement is 3S4Z-1A154-AA. Ford will perform the replacement of parts under provisions of the bumper to bumper warranty under Technical Service Bulletin T31305.

This is considered a "silent recall" where upon Ford may NOT notify owners of this condition. " ( From 2003........)

This no doubt is the likely problem with your car or it could just be in need of a wheel alignment. In any event the previous owner(s) may never had put the car in for the rear suspension modification.
If the fix was undertaken, Ford will have a record of it under your Vehicle Identification Number(VIN).

As the car is out of warranty and given the age(2002 model) I expect you will have to pay for the fix if the problem is the suspension components and not simply the car being in need of a wheel alignment which routinely needs to be done every 12000 miles or so in any event.

Hope this helps.

Take it to a alignment shop they well in California usually charge $45 to $75 and trust me its not something you want to attempt on your own.

I am not an Mercedes expert, but if your rear axle is not solid from one side to the other, you have one of a number of hinged floating rear axles. These may simply require an alignment, just as the front end requires.

With excess wear on the inside track of the tires, the inside of the tire is pitched down lower than the outside edge. Most rear tires are set to run level or slightly pitched to improve handling.

If your rear assembly is not adjustable, the connecting bushings are worn on the linked suspension or the rear axle bearings have excess clearance.

Go somewhere to have a 4 wheel alignment, not to be confused with 4 wheel drive.

Please rate my info.

I'm guessing the lower ball joints are shot. This will cause the tires to lean in on the top and and wear the inside of the tire. I could be wrong! Try jacking the front wheels up and support the vehicle on jack stands, now grab the tire top and bottom and try to rock it in and out. If there is movement, you will have to have someone watch to see what is moving, while you rock it. If it's the ball joints, they will need to be replaced before you can align it. This can be spendy, there's a lot of labor involved.

you need an alignment. Its a toe-in, your tie rods need to adjusted. Check your tire pressure too.

the front end will need alignment kits installed that allow for the adjustment to be made to correct the tire wear, this has to be done on a alignment machine to set correctly, just eye balling it is not an option.

vfdf4: your truck has a torsion bar suspension. This is why you don't see any springs. Depending on the amount of drop you are talking about, there is some degree of adjustment to correct ride height. If you look under the truck closely at the lower control arms, you will notice that there are long steel rods roughly 11/4 inches in diameter which attach from the rear of the control arms and go approximately to the back end of the transmission where they have what appears to be a small arm coming off each one.
There are bolts going thorough each one with locking nuts. By drawing the bolt towards you, it will raise the vehicle.
If there is no significant difference, a few inches the adjustment can be made. HOWEVER, before doing this, check the following. Make sure all the tires are the same size or at least, the tire sizes are the same size on both sides in the rear and the same size on both sides in the front although they may differ in size between front and rear. The tires ideally should be the same brand, same tread and roughly same amount of wear. Set the tire pressures equally. Check the distance between the rear axle or control arm and the body on both sides to confirm that the problem is not sourced from the rear. The distances should be the same on both sides. It is not uncommon for a sagging front end to be diagnosed as a front end problem when it is in fact coming from the rear OR the vehicl has a load which has not been taken into account.. Once you are satisfied everything is correct, at that point you can make the adjustment. You can determine the distance from under the truck by looking at the distance of the top of the front control arm in relation to the snubbers on the frame.
NOTE: The truck must be on the ground sitting in a laden position, no load in the bed or interior. Ideally it should have the front wheels on radius plates which allow for full and unrestricted movement of the front suspension during the adjustment. If you don't have radius plates, you can use a thick piece of cardboard and wheel bearing grease spread on the under side of the cardboard which will sit on the floor. The floor must be fairly smooth or this little trick won't work. If you have to draw up more than 40% of the total distance of the adjusting bolt, the torsion bar is too far gone to use.
I have seen plenty of people **** them up further, but have not known if they have had lasting effects. The front end must be aligned. This answer has been supplied by mybunkey, a Nissan master tech from the old school. I hope I have answered your question sufficiently.

Sounds like your alignment is out, take it and get it balanced, If not that then something has broken in the rear end causing your tire to wear wrong

REAR WHEEL ALIGNMENT
TOE-IN : 0±2 mm (0±0.08 in.)
1. The rear suspension lower arm mounting cam bolt should be turned an equal amount on both sides during adjustment. Right wheel : Clockwise direction : toe-in Left wheel : Clockwise direction : ton-out Maximum difference between LH and RH : 3mm 2. The cam bolt should be adjusted within a 90° range left or right from the center position. CAMBER Standard value : 0°±30´ Maximum difference between LH and RH : 3mm : 0±2 mm (0±0.08 in.) 1. The rear suspension upper arm mounting cam bolt should be turned an equal amount on both sides during adjustment. 2. Install the left and right springs which have the same identification color. 3. The cam bolt should be adjusted within a 90° range left and right from the center position. TIRE WEAR 1. Measure the tread depth of the tires. Tread depth of tire [Limit] : 1.6 mm (0.06 in.) 2. If the remaining tread depth is less than the limit, replace the tire. When the tread depth of the tire is reduced to 1.6 mm (0.06 in.) or less, the wear indicators will appear.
