Default 1980 L48 sagging / Low rear end / photo

Hello , I have noticed that my rear end seems pretty low . When I go over bumps and not really big bumps the vehicle really give me a jolt .

I am thinking new rear spring or possibly and adjustment to the spring ?

I would like to get this fixed asap as everything else is up to snuff .

Thanks in advance

leave the car upside down. takes weight off the springs... shorter spring mount bolts will raise the rear end. if spring is shot, it will need replaced, but this stopgap may get you through a while. cuz once you start unbolting the rear spring, next thing you know you are rebuilding trailing arms, diff, brakes...

Just my opinion, get rid of that collapsed composite spring in favour of a new 9 leaf steel spring, i did that this past fall. Car rides way better and doesnt bottom out.

That happened to me in 1980, I had put new mufflers on my '71 and drove it to work. A black plastic bag blew under it and stuck to the right rear muffler.

well if you want a stiff ride go with the steel spring ,if you want a nice ride go with the composite spring,around 1980 or 81 the composite spring was a standard item.Oh you might want to tip your car back on the wheels ,or you are gonna spill gas!!!

Yes , I have seen some of the posts on this subject . I will talk to my mechanic and make a decision this week . I just wanted to make sure the spring is what the problem is .

Its crazy , I have a MacBook now and I am having this photo issue . Oh well , I guess I will figure it out one day .

I now know where part of my tax return is going !!!!

Off topic but of GREAT importance: Check those tires of yours now...were you aware there is an active recall on the Cooper Cobra GT's???

Take a look here --> U.S. Tire Manufacturers Association Tire Recalls

You'll have to look at the D.O.T. codes on your tires and compare.

Regards,

Dave

Dave , thank you very much . I just checked my tires and they are 255/60/15 and are not on the list .

Good heads up though , I could have easily been on that list .

Thanks again , Chris

Awesome news Chris!!

We're all in this together...things work best when we all keep an eye out for one another.

Glad to hear you're in the clear...now, back to your original "programming"!

Dave

Get Longer Bolts on the rear leaf and install them.

Its counter intuitive how there adjusted .

Loosening nut/washer raises the car BODY up (lefty loosie)

Tightening the bolt washer ( Righty tighty) draws the body down and will make it sight as you see in your photos .

I had a roughly 6" long bolt to begin and I installed 8.5 inch bolts which allowed the car to sit where it needed to be

Hard to tell from the picture, but is the tire/wheel vertical or tilted inward at the top (camber)?
