Ohlins Strut Rebuild

Repair on Ohlins strut




Remove the old strut by removing the two bolts that connect it to the steering knuckle. Let the knuckle drop out of the way. Then remove the swaybar endlink(16mm socket and 17mm wrench). Now, remove the 3 13mm bolts on the top of the strut tower and slowly work the strut out. You will now need to place the strut a bench vise and compress the springs. Once the spring is compressed, loosen the strut bearing retaining nut. Volvo makes a special tool for this, but if you don't have it, a lagre set of vise grips and a combination wrench will do. When the nut is off, there is another retaining nut with 4 tabs, w/ the vise grib holding the piston shaft, tap on the nut with a hammer till it loosens(there is also a volvo tool for this). Remove the nut, then the sturt bearing(ie strut mount) and slide the spring off.

Now, place the ohlin in the vise.....

Now MAKE SURE YOU KEEP THE PISTON AND BUSHING CLEAN!!! THIS IS VERY IMPORTANT.
Now you can place the spring on the spring perch and slide the piston back into the housing. Becareful, it's not hard but just make sure to take your time.

When you get the piston back in, put the retaining nut back on the bottom of the strut. Tighten to 50Nm or 37 lb. ft. Release spring clamps and make sure the strut bearing seats properly.

Then slide the reservoir through the shock tower and align the bolts with the holes on the tower. Push it up and throw a nut on one of the screws so the shock is held in place. bolt the shock back up to the steering knuckle and tighten to 52lb ft and then 90* on top of that. tighten strut tower bolts to 18lb ft. and you are done. Go get an alignment.

DO NOT ADJUST THE POSITION OF THE HOSE ON THE RESERVOIR UNLESS DONE BY AN OHLINS PROFESSIONAL REPAIR CENTER
