Just removed and disassembled all four struts and will be replacing the shocks and springs. I was using the MSA urethane bump stops which seem to be very firm, so I am considering switching to KONI bump stops when I reassemble as they seem to be fairly soft for the first inch of compression according to the published compression vs. force curve. In couldn't find anything searching this forum and am looking for real world feedback/experience with the KONI bump stops. Thanks, John

So my local Z buddy @GGRIII got his 74 260Z on the road and we drove that to Zcon. During the short shake down testing, one of the things we noticed was that the steering effort was significantly lighter in his 260 compared to my 77 280. And then (thanks to other forum members @Zup and @wal280z ), I got the pleasure to drive a 240 and another 77 280 at Zcon for a larger sample size. The steering effort was consistent, meaning that the 77 280 took way more steering effort than the earlier years. Now, some of this could be attributable to suspension mods and tire choice, but it's stark. Once you're moving, it's no big deal, but maneuvering in a parking lot at a crawl, …

The front sway bar mounts to the frame with a thin piece of metal between the two. I'm not exactly sure what they were thinking when they put that thin piece in there, but here's what the originals look. Note that the shape changed over the years... The 240 parts is smaller than the 260-280, but here's what it looks like on the 260-280: Unfortunately, the pieces on my buddies 260 don't look so good. His plates are rusty and bent: So I had replacements laser cut out of 304 stainless. Nice new shiny parts: Hey, it's the little things, right?

Hi, Did someone faced the same issue??? New KYB with right reference at their respective position front/rear. + Vogtland springs with right reference = Spring gap of 0,5 inch for the rear, and bit less for the front Carbody shop refused to install them pretending it was too dangerous... Does the strut spacer needs to be removed? Is that safe? Thanks for ideas and experience sharing Seb

I need your advice regarding my '72 240Z. Can't get either of my front end strut inserts out of their strut housing after I removed the gland nut. They should just slip out. They do not. Perhaps they are rusted in? I've saturated them in penetrant, heated the housings with a propane torch, tapped the housings with a hammer, and of course pulled on 'em like crazy. Got any ideas for me, please?

Hello. I bought replacement KYB's 361001 for the rear of my '73 Z. The blown struts are also KYB same number stamped on. Those slide in and out no problem. The new ones refuse to slide in and seize up well before reaching half way. Any help in figuring this out why what should be the same product does not fit would be appreciated.

Hey guys, I have a 240Z 1973, bought it from Germany in February. The previous owner got a electric power steering installed (unfortunately cannot get any knowledge from him..). This power steering was working when I got the car, but now, since I installed some additional gauges and other electrical stuff in the car, it doesn't work anymore.. I found at least one loose (black) wire and automatically thought it is the ground, installed it to the ground, but the power steering still does not work.. A box of it has a sticker saying "easydriveusa.com" on it. Tried to google to find a wiring diagram for it, but no hits what so ever got... Has anyone of yo…

Hello, since I am currently restoring my 1973 240z and the l24 engine will get pulled out I am considering doing some performance mods. I have found that installing a crank with a higher stroke is a common way to get some extra power but i am not sure if it would be smarter to use a regular l28 crank (like the l26 did i believe) or the diesel ld28 crank and if this would even fit/work? Thanks for the help in advance. Greetings from Germany.

Hi all, Recently pass smog test. Been enjoying it every chance I get. Even volunteer to do errands for wife just so I can drive it!!!! I've notice the steering wheel can only make one full circle and the "distance/length" of the tire doesn't cover much. to put it into perspective, I'm having trouble making a 2 lands U-turn. What I mean is the other day I at McDonald's drive through, I had trouble making a right U-turn. My Van and sedan seem able to make a right U-turn quite easily. Of course it inches outside toward the other land a bit, but not as much as the Datsun. I had to back-up a bit in order to make a turn. I had to make a three-point…

Why... BRAND NEW spindle pin from all appearances - can't get it out. Whomever installed this (these - other side was "replaced" as well): A. OVERTIGHTENED the lock bolt B. A little lubricant would have been nice or maybe some ANTI-SEIZE... Now I'm going to have to saw these once perfectly good spindle pins and press the centers out... I can guarantee you that these pins will be mushroomed in the middle because the installer didn't position the pin properly and OVERTIGHTENED the lock pin! PLEASE stop doing that!! I understand that not everyone knows the value of anti-seize but given the level of frustration the spindle pins usually deliver, it sho…

Did the original 240Z Nissan U Joints on the half shafts have grease fittings?

Hey Guys, Replacing old rubber Sway Bar Link Ends this week with new Poly ones. QQ: How flush is the bushing supposed to sit on the sway bar? The old rubber ones contoured to the curve of the metal of the bar, but mostly because they were 43 years old and absolutely shot. As I am tightening the poly ones, they don't have as much flexibility and so they don't align as nicely. I assume this is okay, but wanted to check first before hitting the road. (Disclaimer: Sway bar ends are not tightened in the photos. Took the photo when I first put them in place, but forgot to take a tighted photo before leaving the shop.)
