928 struts
My next project is to get the rear struts replaced on my 928. Does this require any special tools besides a spring compressor? Is it that hard of a job? Any info would be helpful.

get a copy of the workshop manuals, most of your questions will be answered in them

I recently changed over the entire front and rear suspension from one 928 to another. This was not as difficult as I first imagined and on the front the spings and struts could be unbolted and dropped out without spring compressors. On the rear I think you will be able to follow this paste from Greg Nicols fantastic site.
’87-’95 Porsche 928 Strut & Spring R/R (Earl Gillstrom and Gary Knox 12/04) This replacement procedure has been adapted from write-ups of several who have done the R/R before. It includes our learnings from four replacements that the two of us have done together. We think it is pretty thorough, and hope you agree. IF the replacement strut/spring sets are fully assembled, removal of the “old” units and replacement with the “new” assembled units by 2 people should require ~1 hour for both rears, and ~2-3 hours for both fronts. Another 2-4 hours may be required to R/R all 4 units if each strut/spring is being disassembled and re-assembled with a new shock or spring. Be sure your adjusting perches are operable and well lubricated before you reassemble a unit. Note that spring compression and disassembly is a dangerous job. Use proper tools and techniques. Paying a shop to do this could prevent SERIUS injury if you do not have proper tools, or are inexperienced. ----------------------------------------------------------------------------------------------------------- Note: (xx mm) indicates wrench size, and {xx ft lbs} is torque spec. REAR - Removal: Loosen rear lug nuts {re-torque these {96 ft lbs} when re-installing} Jack car up and put jack stands under car for safety Remove rear wheel(s) Put Penephite (or a good liquid wrench type lubricant) on threads of all bolts with nuts to be removed and let set for ~10 minutes From inside rear hatch, remove 3 nuts on each side behind rear seats that hold the top of the rear struts (17 mm). {Re-torque {34 ft lbs} when re-installing}. Remove FRONT nut (NOT the rear one) on the long bolt that supports bottom of strut/spring. Nut is just behind front side of rear brake rotor (22mm). Remove sway bar drop link from attachment near rear of the bolt holding rear lower arm in place (19 mm). Use a Vise-Grip wrench to grip the REAR nut on the large long bolt that holds bottom of strut to the lower suspension arm. Pull this bolt out the back. {Re-torque this bolt {103 ft lbs} when re-installing}. Pull bottom of the strut toward outside of car and lower suspension arm down. Pull strut/spring down and out. (Watch where the three washers come from that are used in this connection!!). ---------- Fini!!! |
