I bought a set of the rubber rear trailing arm bushings in the 914Rubber GB when they first came out (can't remember when that was). I am just now getting around to installing them and ran into a problem. I did a test fit to see how hard they would be to install and was shocked to find I could easily slide them into the trailing arms by hand AND could slide the pivot shaft in by hand. In fact, I'm not seeing much difference from the polygraphite bushings they are meant to replace. If anything, these fit even looser. I'm wondering I was sent the wrong ones. My understanding is the rubber bushings should be a tight fit and require a press or similar to install as seen in Ian's video. Is there a good way to know what I have? These are stamped "WDG" on the flange side which is different from the stamping on the first set of bushings I bought. |

Rut Roh!
Could it be that you're using the 914Rubber bushings with the OEM pivot shafts rather than the heavy 914Rubber SS pivots? Maybe the SS pivot shafts are larger OD than OEM? |

Rut Roh! Could it be that you're using the 914Rubber bushings with the OEM pivot shafts rather than the heavy 914Rubber SS pivots? Maybe the SS pivot shafts are larger OD than OEM? Exactly my next question. I just rechecked all the bushings and there is something seriously wrong here. I checked all of the bushings and all are a snug, hand-press fit into the trailing arm bores. Then the shafts either slide right in with no effort (as in, they will drop in with gravity alone) or require only moderate hand pressure to press them in without lubrication. In the worst case, there is even noticeable play after the shaft is installed. The only things I can think are that either the rubber shrank, or the bushings were designed for the SS pivots and those have a larger OD than stock. I just swapped my SS pivots with another member for a set of pristine OE shafts because I couldn't justify the extra weight for a street ride so I can't check.
