Replacing Leaf Springs
« on: March 21, 2007, 01:17:32 PM »
Hi,

I am in the process of replacing my leaf springs, and things arent going well  :'(

I have finally removed the anchor plate, the bracket that holds the front of the leaf spring to the car and also the shackle (top and bottom), but Im still not able to get the leaf springs out.  When I lower the axle to release the tension in the spring, the sway bar seems to get in the way.

I have read a couple of articles on removing the rear leafs (including Hitmans) and none of them mention the sway bar.  Any help/advice would be appreciated.

Thanks in advance.

when u removed the shock plate that holds the rear end to the leaf spring the sway bar should have came off with the plate so once u ahve both the front spring perch and rear shackle unbolted from the car the spring should just fall out

Once you remove all 4 nuts from each shock mount plate and remove the shock jack up just the axle and the leave spring should slip out of the tunnel they rest in. Remove the front bolts to the front spring bracket and then work on getting the rear of the springs out by removing the bolts that run through the eye of the rear of the spring.

PS. Have you ever replaced these bushing?  ;D

Hi, thanks for the replies.

I have only owned the car a couple of years, but I dont think the bushes have ever been replaced, I am doing that as I replace the springs.

I did get the impression from articles that I had read, that the spring should just drop out.  But when I jack up just the axle, the spring jacks up with it.

I guess 30 odd years of road grime makes a pretty good adhesive !!

I am doing the same thing on my 78.  I took the rear sway bar off as it would have interferred with removing the springs and the rear.  It is easy to remove the sway bar, there are two bolts that mount it to the underneath of the car.  Remove them and the sway bar should come out since you have the spring brackets.

Good luck.

You may need to use a prybar to get the springs to drop out of the brackets on the rear end. If you've removed the rear plates, shocks and sway bar you should be loose. You may need to pry a little. This is the easy part. Wait until you try to get those old bushings out!  :o

Well, I did manage to get the leaf spring out, took a couple of hits with a large hammer  ;D

As for the old bushes, the shackle bushes came out surprising easy, however the bolt holding the front of the leaf spring to the bracket, that took some work.  Oh well now the fun starts - putting it all back together.

if your doing it with your springs and everything in the car then you will need a good heavy duty prybar....but if you had everything out from underneith of the car then a mighty sledgehammer will do the trick....thats how mine had to come apart...i got new springs anyway, just beat the old ones till they fell out of the hole....

Glad to see that your front bushings came out easily! I've never been so lucky. I've always had to press mine out. Good for you! Glad to know some peoples projects go better than mine.  ;D
