Replacing 63-82 Corvette Leaf Spring BUSHINGS
HTML-код
- Опубликовано: 18 ноя 2024
- For the most part, C2 and C3 Corvettes share identical frames (for the most part), and this video may benefit those needing to replace the leaf spring bushings.
The job is not difficult, per se, but having a portable lift made my work much easier. It can also be done with a floor jack and jack stands.
The bushings on my 1976 Corvette had disintegrated, and that's not uncommon with polyurethane (or poly, for short). Rubber bushings deform over time but don't crumble like their poly counterparts.
I did use the rubber bushings I had recently removed from my 81 Corvette since they were in acceptable condition, but this was mostly a stopgap measure as I intend to completely remove the rear suspension on my 76 Vette so I can rebuild the trailing arms, the half-shafts, and much more.
I hope you find the video helpful if you need to replace your leaf spring link bushings.
Thank you for watching! 🙂👍🏻

I miss your narrative and your way of explaining things. Silence is good, but I’m here to listen to your thoughts and opinions. Thanks for all the great info and insight .
Your videos really are terrific. Every time I watch one of your videos I think “I could do that.” It’s rather inspiring. I agree with many others here, that your commentary is usually very helpful and you have a good sense of humor.😊
I appreciate the kind comments, and glad to hear my videos are helpful. Thank you for watching! 😊👍🏻
This is the PERFECT video for what I need to do to my 79. I took it apart months ago then got sick. I am just getting back to it and forgot stuff. This shows me 100%. Thank you very much!
Glad to hear my video was helpful. Thank you for watching! 😊👍🏻
I also miss the narrative. Your English is very clear, no problem for most guys where you know a bit of English. RUclips also have automatic subtitles, which work very well with clear pronunciation.
Excellent work
Awesome job! Awesome tutorial!👍
Thanks for another great video. I also enjoy your comments and explanations. Bring them back if you can.
Very nice informative video.😊
They make a tool to crimp the flange washers on to the spring and I use white vinegar to derust parts it’s cheap and. Works excelent enjoy your vids Am restoring a 69 and67 bb corvettes
Cut the leg of the cotter pin that is bent over the end of the bolt half way across the bolt end. Leaving the cut end past the edge of the bolt is sharpe and can rip your skin. Good video and nice car.
Good video.
You want to avoid polyurethane bushings in every context, except maybe in a race car. They degrade in 2-3 years no matter how well you keep the car to became a brittle mess as that one. Rubber bushings lasts way longer... BTW you have one of the best Corvette DIY channels of youtube!
Thank you! 😊👍🏻
To quote Red Green... "spare the duct tape, spoil the job" :-)
Hey Luis, another great video. I do miss your narration of your work. Did the lowering bolts drop the rear an inch or so? You have an excellent way of calmly describing the good and the bad of C3 repair. Love your cleanliness and quality work. Even your jack is spotless! Have a great day.
Yeah, I’ve been experimenting with no-narration videos since they’re actually shorter and they do not require translation for viewers of non-English-speaking countries.
The lowering bolts did drop the rear about an inch, but you always have to take into account the tire profile.
My 76 was already lowered and I used the factory leaf spring bolts to show the differences. And I prefer the castellated nuts with cotter pins versus un-drilled bolts. 😊👍🏻
I wish you were my neighbor.
Amen
LOU ,INFORMATIVE VIDEO , WHERE DID YOU PURCHASE THE EXTENDED LOWERING BOLT & BUSHING KIT ?? PLEASE LET ME KNOW ? THANKS JESSE VIA LAS VEGAS

great video, so using that rust remover on the washers is better than removing the rust with a wire wheel?
I clean them before applying the rust remover, which also neutralizes any rust hiding in hard-to-reach areas. 😊👍🏻
I see you are using a Quick Jack. I was wondering how you like it and which model you have? I’m considering buying one and wondering if you would recommend it?
One of my best investments. Mine is the QuickJack BL-5000SLX ruclips.net/video/yjYh_8cUevE/видео.htmlsi=m1wChGnH6-xNPKHf
Not sure about your year corvette but on my 69 the metal straps on the rear leaf spring should be removed. They are only there during shipping and get removed after installation. Thanks for this video.
I’ve heard that before and I think it’s science fiction. I’ve seen similar straps on almost every leaf spring, so mine are staying on. Thank you for watching! 😊👍🏻
Did you do the under coat yourself? If so did you take off the body? Looks great. Thanks
Parts of it, but a while ago. And not a frame-off. Thank you for watching! 😊👍🏻
Did you paint the retainers and washers? They look like you coated them with some kind of paint. If so what did you use?
I coated the parts with Loctite Extend Rust Neutralizer amzn.to/4hH7ofO
At ~4:55 when you first start to jack up the right rear hub & trailing arm it appears there's a very noticeable camber change of the hub and trailing arm before they start to lift. Is something in that system worn, or too much play in the diff?
I'm curious because I'm getting ready to do an alignment on a '66, after changing some bushings. I'll have to watch mine closely to see if I see the same thing.
The rotors are not riveted so that causes the movement you see.
Does your 76 have a 7 or 9 leaf spring? My 77 rear suspension is worn out and the spring and half shafts are bent upwards. What spring would you recommend 7/9 leaf or composite?
My 76 has a 9-leaf spring. I’ve heard people give composite springs great reviews, but I have no experience with them so I cannot tell you which one to choose. 😊👍🏻
@@76vettethanks, was thinking about trying the 7 leaf or a low arch comp. Don’t want to have to deal with a ride height issue.
This maybe a stupid question but not sure why you have clamps on the leaf spring?
Good question! Without them the jack can slide with dangerous and/or disastrous results. 😊👍🏻
Ok I missed that the clamp was supporting the jack on the inside edge! Now you have motivated me to do mine!☺️
Great video however why not change the rubber cushions . There very inexpensive about 7.00 bucks apiece
