RogerH Posted May 11, 2018 Report Share Posted May 11, 2018 Hi Folks, I have an odd rattle in my 4A. It lurks somewhere behind the dashboard. I also have an odd problem with the wipers every now and then they stop working. A quick flick of a blade gets them going again. Yesterday I had the idea that perhaps they were related. Today I removed all the parts to enable removal of the wiper wheelbox covers. When the covers were removed - lo and behold - everything appeared normal (bu99er) Upon reassembly I dropped one of the speedo attachment nuts. Did it fall onto the rubber mat - no Did it fall onto the top of a wire loom - no Did it fall - yes Which direction - probably up if I know my luck (not been a good couple of days) OK, not a major disaster. I'll make another one. What is the thread size. I had an inkling that ot was 3BA. My newish Zeus book only gives tapping sizes - no other data. Thankfully I have an old Zeus book. It confirms it could be 3BA. My thread gauges don;t fit the thread. BA threads are very strange (6BA is the perfect thread shape). Thankfully I do have 3BA taps - the threads to line up. 10 minutes on the lathe and I have a new nut. I shall now go out to the car to fit the new nut and expect to find the old nut on the rubber mat. Roger Quote Link to post Share on other sites
stillp Posted May 11, 2018 Report Share Posted May 11, 2018 I bet that odd rattle is a spare speedo nut. Pete Quote Link to post Share on other sites
ChrisR-4A Posted May 11, 2018 Report Share Posted May 11, 2018 (edited) You will have 2 rattles now ???????? Try a magnetic probe will prob find them both. Also check glovebox lid stay. Chris Edited May 11, 2018 by potts4a Quote Link to post Share on other sites
RogerH Posted May 11, 2018 Author Report Share Posted May 11, 2018 Hi Chris, the nuts are Ali so the magnetic will not work. I'm sure if I did use the magnet then end would fall off and stay with the nuts. The mystery continues. Roger Quote Link to post Share on other sites
peejay4A Posted May 11, 2018 Report Share Posted May 11, 2018 Send me the rattle. After driving home from the museum the other day by the back roads Eric now has quite a few new ones so another one will not make a difference. Quote Link to post Share on other sites

Lebro Posted May 11, 2018 Report Share Posted May 11, 2018 I have noticed a rattle recently somewhere near the bulkhead. A search under the bonnet for anything loose did not find anything, Rattle still there today, felt under the dash while driving, Found it ! It was the two flaps on the heater just touching each other when fully open. Rattle now gone. Bob. Quote Link to post Share on other sites

ChrisR-4A Posted May 11, 2018 Report Share Posted May 11, 2018 When I had a rattle it turned out to be the brake pipe running across the bulkhead under the bonnet but sounded just like it was under the dash. Give it 3 or 4 months and you will either find it or another louder one will develop and drown it out!???????? Quote Link to post Share on other sites
Paul J Posted May 11, 2018 Report Share Posted May 11, 2018 Try dropping another Roger and watch where it goes it may lead you to a nest of them Quote Link to post Share on other sites
ChrisR-4A Posted May 11, 2018 Report Share Posted May 11, 2018 Maybe it's age related Roger, we all loose our nuts in the end, so I'm told ???? Quote Link to post Share on other sites

Paul Heritage2 Posted May 12, 2018 Report Share Posted May 12, 2018 My rattles are always shortly after placing spare coins and/or screws and bolts in the ashtray, and then forgetting I put them there LOL Quote Link to post Share on other sites
