Just a few basic questions:
1) Do the rubber bushings I circled need to be changed? None are cracked or damaged, but are they just spacers or do they affect how tightly the car handles? 2) Plan on replacing shocks with Bilstein shocks. Can I reuse the top hardware shown or must I acquire new parts? If so, where would one purchase said parts? 3) Is there a recommendation for a rear trailing arm rebuilder in the San Diego area? I need new rubber bushings, new bearings, and my hubs pressed back in. I know many do it themselves, but after reading some of the recent posts I'm a bit intimidated.

I just want to verify a few things before I mount the rear trailing arms:
1) In theory are these shaft splines suppose to bind against the suspension ear and part #5 so the shaft stays stationary and the rubber bushing rotates with the arm during operation? 2) Is washer #8 the only washer in the shaft assembly? It's the only one I remember taking off, but it seems strange there isn't one between the nut(#7) and part #5. 3) Are both shafts torqued to 108 ft-lb? 4) I bought this rear sway bar bushing from 914Rubber. Does it need to be cut or is there some creative way of slipping it onto the sway bar? |

I just want to verify a few things before I mount the rear trailing arms: 1) In theory are these shaft splines suppose to bind against the suspension ear and part #5 so the shaft stays stationary and the rubber bushing rotates with the arm during operation? That is my interpretation of how it works. QUOTE 2) Is washer #8 the only washer in the shaft assembly? It's the only one I remember taking off, but it seems strange there isn't one between the nut(#7) and part #5. The washer isn't needed on the outer side because the bearing (part #5) acts as its own washer. QUOTE 3) Are both shafts torqued to 108 ft-lb? No. The outside bolted to part#5 gets 108 ft-lbs., but the inner on the ear only gets 87 ft-lbs. It takes a little deciphering to get that out of the factory manual, but that's what it says. QUOTE 4) I bought this rear sway bar bushing from 914Rubber. Does it need to be cut or is there some creative way of slipping it onto the sway bar? Hmm. Yes, it should be split but my 914Rubber bushing came already split. (IMG:style_emoticons/default/confused24.gif) Use synthetic (non-petroleum, e.g. pure silicone) grease on those bushings. |
