Hello all from Pittsburgh (temp in the 50's and no sun today) I've run across a modification in the attachment of my left front upper control arm and wonder if this arrangement is known to the list.
You were lucky to find this before it found you! Just a guess, but I would guess that the original, tapped holes on the control arm were stripped out at some point, after which the PO took the path

Hello from San Diego 70's (Burr) and clear 8.8 are only SAE grade 5 bolts. !!!!!! Use 10.9 bolts or SAE grade 8 for suspension !!!!!!! I have seen that done on race cars to get full back caster with
WAIT! Grade 8 bolts are stronger in tension, but are more brittle than Grade 5 and are not as well suited to shear loading, especially single shear. If you want bolts that are better than stock, get
Metric grade 8.8 is roughly equivalent to grade 5. Go to your local fastener store (not hardware store, fastener store) and ask for grade 9, or at least metric 10.9 (equivalent to grade 8) The upper
With all the discussion about the metric bolts for the upper control arms on roadsters I think that none should be used. The bolts on the upper control arm on roadsters have SAE threads and should be
wait again mark there is very little shear load on the bolts that hold the upper spindle to the car frame , since the upper a arm pivots on the shaft, and the geometry of the pivot pt to the action o
Hi All, Just a short take on the ongoing debate about the failure of these upper control arm bolts. One should be able to tell from the broken surface what method of failure has occurred. If the bolt
Of general interest, I stopped by my local metal scrap yard yesterday. I am always looking for 6061-T6 end pieces. In the process of scouting the yard, was a VG30T engine sitting there. Hmm, the end

Tom, et al This is a classic example of a brittle failure as a result of a high applied torque, and the fact that it started at an oil passage hole is not surprising, either. I think it would be a go
When I worked for Nissan I saw a few VG30 (most were not T or TT) motors shear the end of the crankshaft. This was caused by the radius at the nose of the crankshaft being too sharp, causing a stress
Tom, Just to clarify, the AN standard includes threads per inch and the AN7 is 20 tpi (7/16-20). For what it's worth, virtually every bolt in the front suspension can be replaced with an aircraft sta
I was not addressing a specific bolt either in terms of application or in size/thread pitch. What I was trying to point out is that bolts are built for specific purposes and simply going to an altern
