Default C4 terrible jacking locations

Well, I stumbled upon a very strange situation in looking for a good jack point to lift the rear of my 86. Never have I ever had a vehicle that didn't have a plain just quick run the floor jack under and lift it up. So guess the crossbar adapter is the best solution for this vehicle!

I thought I would use a crossbar as well. I bought one from Harbor Freight and realized it doesn't spread wide enough, had to return it.

You are welcome! You could also go all the way down the rabbit hole like I did and add these.


I love these for oil changes. Next is new shocks and brake bleeding.

Everyone talks about these jacking pucks

ive never understood how a ‘puck’ would make jacking up a c4 easier

Ive seen the photos, still confused thats why ive never done it that way

does a notch need cut in the hockey puck ?

hockey pucks seem hard, non deformable
(which is why they hurt people when they go into the crowds, i believe they’d hurt the rocker panel the same if they can break someone’s face in a crowd)

I just used the standard floor jack with a 2x4 cut wood block into a4x4 inch square

Default Pinch Weld

I've tried many things...regular jacks, hockey pucks, even the Quick Jack

Hockey Pucks: Yes they can be hard on a rocker (I loosen my rockers first when doing it this way)
Quick Jack: Really awesome HOWEVER very heavy and take up a lot of room. They are about 80lb per side so you need to be strong enough to stand up on edge, lift onto hanger ect...and be VERY careful when putting them down on the ground as to not hurt your back. I sold mine after just 1 year...found it took more energy and more time than conventional jacking (and I'm strong and fit...juice just aint worth the squeeze for me)
Pinch Weld pads (see photo): This is what I use now. So flipping easy, can even use the original designed jacking locations. just need to make sure your floor jack clears everything. Disclaimer...I've had many C4's and all are a little different so results vary. I'll sometimes need to put a hockey puck under these pinch weld pads (to clear rockers, lines ect...) but still, it's super easy. You're just lifting then placing stands underneath it's not like you're lifting up then crawling under right??? Safety First!

My understanding is that you do want to place the jacks where they were designed to lift from.

I just leave the Quickjack on the garage floor and park the car over them. There is a recent thread where some HF roller bearings are attached to the base of the QJ. At my age I prefer getting down and up once per side and with the combination of a puck and the smaller of the two supplied rubber lift blocks there is a small gap to the pinch welds i'm trying to line up with. I haven't added the roller bearings yet but plan to soon. Of course that will change the spacing so maybe I won't then need the pucks anymore.
