*admins, please put this where you think it goes. this was the best section I found for it.... Hi guys. So. last year, I changed my front suspension. and as I foolishly turned the wheel hub by hand (with a lot of strenght to overcome resistance), making the rack and pinion move as I did that and and one of the rack and pinion seals blew. Fast forward to this year (cause I'm lazy and didn't do it during the winter), I took the rack out and am rebuilding it. As I did that, I realized my passenger side rack bushing, which has been copiously bathed in engine oil for years, was shot. All mushy and broken. And just my luck, they don't really sell them anywhere, or if they do they charge an arm and a leg for it. or it's just the driver side. or... whatever. So I made one! Here is the crummy one next to the brand new one. I used the measurements from the rack, the old bushing and the bracket that holds the rack in place to 3d design mold, 3d printed it, greased it up with petroleum jelly, and some (not all tha tmuch, actually) 3M windshield urethane (high viscosity, which cures a little harder)... Here are some more shots of it, including fitted on the rack, and with the bracket that holds the rack on.. I'd say the hardness is right on par with the other side's bushing which is old but still looks healthy. Yes the surface finish is a little rough, but it's sound.. I'm happy with it. I'll be putting it back on the car as soon as I motivate my sorry ass to put the rack and pinion back together (btw, used a 55 CAD$ kit, that came with almost all the seals (all the important ones, really), and that worked really well. it's not hard at all following the FSM manual). I'll make certain to wrap it really well in some plastic or another to try to keep the oil off of it (yeah I know I should fix the leak). If I'd have to do it again, I'd try the lower viscosity urethane as this one was a b*tch to get out the tube... if I'd live in the states, I'd buy some pourable 2-part urethane and simply pour it in, but there is none around me, at least not in reasonable quantities at a reasonable price. THAT would be a dream to use... This technique can be done for the other side as well, or any other similar bushing. if anyone is interested I can post pictures of my mold (4 parts), and even share the 3d files. Keep in mind that this bushing is bigger than the driver side (I have the files for 3d printing the other one too) and won't fit older models. Making a new model for a mold for any sort of similar part is a pretty quick affair and printing one in this size was about 6$s worth of plastic. I can also make and sell some, if anyone is in need of one. Questions welcomed. have a good night! s.
tension rod bushings - any source?
supernova_6969 posted a topic in S130 Series - 280ZXhey guys i'm on the market for new tension rod bushing (rubber, ideally), and one of the only place where I found any were these ones.... https://www.thezstore.com/page/TZS/PROD/classic20m02b/23-4322 when I look at them, they look suspiciously like these "Strut Rod Bushing": https://www.rockauto.com/en/catalog/nissan,1983,280zx,2.8l+l6+turbocharged,1209406,suspension,strut+rod+bushing,7608 some of these kits even come complete with the metal sleeve that would fit nowhere on the strut rod, but would totally fit on the tension rod, I think... can anyone confirm my suspicions, that these are the same part, but misnamed in a few places, or that they are the same for both locations? thanks! seb EDIT: you should read this, it`s a short topic, but in essence, the bushings that were suggested to me are a great fit, cheap, and come with the bushing, the metal sleeve and the 2 buig and 2 small washers. great value. Here is ac delco product number, and a link to where I bought then (not affiliate, same link as above). AC delco kit no 45G25036 https://www.rockauto.com/en/catalog/nissan,1983,280zx,2.8l+l6+turbocharged,1209406,suspension,strut+rod+bushing,7608 they got the name wrong, but it`ll fit on most of the older z cars. very neat kit. by the way, anyone not 100% certain about fdoing this should look at this page. great site, great photos,. http://www.atlanticz.ca/zclub/techtips/suspension/comprod/index.html thanks for everyone who joined in.
Rolling with the punches a 75 280Z v8 Refresh
hwvigo posted a topic in S30 Series - 240z, 260z, 280zHello Im Will and this is my 75 280Z the day I recived it as a birthday gift from my dad the the original owner. And this is my dad the day he bought the car in 1975. In 1990 my dad made the choice to do a sbc swap in to his z and this was the result A nice but low cost swap that has stood up to the test of time . Over the years the car has had many different carb setups but this was the state of the motor when I got the Z. And its a bit tired and needs some new life breathed in to it , and thats just what i am going to do . Please feel free to offer helpful tips and tricks and any advice thanks Will S.
hey guys, I am in the process of pulling apart all my lower control arms, steering linkage, rear diff and moustache bar.. I am running a 1JZ with 340whp, an eibach upgrade springs with kyb shocks, I need to replace all my bushings but am kind of stuck as to which way to go.... Please bear in mind I want this as a daily driver with some track days. I don't want my car to rattle, sqeak and feel its vibrating all the time yet I don't want it to be super sloppy. Has anyone done a hybrid bushing replacement? Like some rubber and some poly? I would really appreciate some feedback.
So I have a really loud and awful sounding squeaking noise coming from my rear suspension. it is happening only when I either go over a large bump, or I accelerate. It is BY FAR worse when accelerating, its almost constant squeaking/metal on metal? screeching sound. I'm having a lot of trouble trying to narrow down what could be causing it because I recently replaced all my bushings with urethane bushings, and replaced the struts. I have tried spraying my bushings with silicone spray, but that doesn't really help. I have tried having a passenger crawl back there and see if they can narrow down the problem area while I was driving but met with no success that way. I've tried taking out all the rear interior and driving with the hatch open but that did nothing. I've tried pulling the driver's side LCA (I'm convinced its on the driver's side... at least mostly) and re-greasing and sanding down the bushings to make them fit better, but that did nothing either. What could be causing a squeak under acceleration? Which bushings should I look at? Is it possible its the springs scraping the spring perch? Is there supposed to be some kind of pad between the two? Its SO BAD when accelerating, even like 1/8th gas it will do it. But cruising and braking it is silent. Any insight would be much appreciated. I apologize if this is in the wrong section, but I figure that since I have a 280z, this issue would be specific to that car, Mods please move if this is in the wrong section.
