Front Springs?
« on: September 18, 2005, 15:33:28 »
My left front side sits ~1+ inches lower than my right side.  Car is tilted!

 :?: If I need to replace the spring on my left side, do I need to replace the right side also at the same time?  In other words...  do these need to be done in pairs? :oops:

Thanks,
Bob

I've still not seen consensus on whether these springs ever wear out - many contend they never do. So unless one of yours is clearly broken somehow, I suggest looking into some other possible culprits first, like the pads that are on top of the shocks, or you might even check the rear of the car, how the suspension is looking there: also here there are pads, donuts at the trailing arms, etc. (because I recall Jim Villers telling us that his front was too high not because there was anything wrong with the front suspension but, rather, because his rear suspension was sitting too low).

But if I were replacing a spring because it was broken, I would go for all four, just to get it done and over with. If you go that route, I would suggest carefully matching the new ones to the old ones, or else you could be battling another ride height issue for a while.

Hi Cees!

I have already replaced both rear spring pads, the center rear differential mount, and the trailing arm bushings, donuts.  So, in summary, my rear seems to be ok.

My problem is that the drivers side front in 1+ inches lower than the passenger side.  I would like to even this up.

Does anyone else have any suggestions?

Thanks!

Bob ... One solution would be to add "rubber spacers" to the driver's side to raise it up.   The rubber spacer to adjust the ride height was from http://www.mcmaster.com/ Item 9774K48; SBR Rubber Flange Gasket 3" Nominal Pipe, 3-1/2" ID, 5-3/8" OD, 1/8" Thick. $2.76 per Pack of 6.

I would also look at the rear to see if there is a problem there (sagging in the left rear can appear to be a too high in the right front)

Hi Bob,

Maybe Arthur will chime in here.  He seems to be a suspension wiz.  I know there are spring pads on top of the from springs.  Mine were in pretty good shape because they are up high and protected from the elements.  They come is different thicknesses although an inch sounds like its off more than the max to min thickness pad.  How is the other side?  I suspect it's good or you would have said something.  I was thinking maybe a thin pad on the passenger side and a thick pad on driver.  I'm sure you could add an additional thick hard rubber ot top to help compensate.  The bottom of the top spring pad is shaped to fit over the end of the spring.  The top side of the pad is flat.  I would consider adding a 1" pad on the driver side.

Thanks Guys!

I will focus 1st on the rubber pads, vs assuming that the springs are weak.

I'll order the rubber and let you know how it ends up.

Thanks again!

One would think the drivers side would wear or drop first(car always has the weight of a driver, not always a passenger)Could you just swap driver's spring with the passenger side spring?

Update....

A while back I replaced my front spring pads with new 30mm pads.  While this did even out both sides, my car sat high, too high!

This morning, I pulled out both front springs and sawed off one spring ring from the top of each spring.  With one ring removed, my car now sits approx 2 inches lower in front.  While this may seem like a lot, the new ride height looks perfect!  I drove the car this afternoon, and I am very happy with the results.

The new height is 13.5 inches, measured from the center of the star on the wheel cover to the lowest point on the fenders.

Bob, Thanks for the follow-up to an interesting ride height problem. Your solution was a very courageous one!     Jim Pancoast

Hi Jim!

Happy to share with you and the group...

Cutting one ring from each of my front springs was not something I would have done a year ago.  I tried many things (as you know) to correct my ride height issue and also the fact that one side was higher than the other.  Before I did this radicle procedure... I removed the "spring cheater nuts" installed by a previous owner; replaced the front rubber spring donuts; replaced the subframe mounts; replaced the kingpins and all other bushings; I also replaced the rear rubber spring donuts, trailing arm bushings, etc.. Alignment done 2x's...

The reason I point this out is that I did everything else 1st (all normal replacement items) before making the decision to cut the springs.  Not sure why I had to do this to get my front end lowered?  Others with similar ride height problems may be lucky in simply replacing the above mentioned items?

Regards,
Bob
