I just got my car back after Monroe Quickstruts were installed on all 4 corners.
In case you haven't read before, mine is a 2004 SES without SAS
. 70k and mainly garaged in California. Only the front struts needed replacing but I took the advice here and replaced the rear as well. I opted to go for quick struts as there was a deal and I thought it better to replace as many parts as possible if I'm paying for the labor anyhow.
My mechanic said that all other suspension components looked fine. This makes sense to me as I only have 70k and haven't driven much on the worn out struts once I noticed they were going. I have the old rear pinch bolts and they don't look nearly as bad as the picture of 8 year old CA ones posted in other threads. So it seems my garaging is helping here as well as generally lower mileage.
However, I immediately noticed that the left rear is sitting lower than before and lower than the right rear.
I measured with and without a 150lb weight in the trunk. These are the ride heights:
Rear Right with 150lbs total weight in trunk: 69
Rear Left with 150lbs total weight in trunk: 67
Rear Right with nothing in trunk: 70.3
Rear Left with nothing in trunk: 68.3
So in other words:
a) Left is 2cm lower than Right
b) The springs on both sides seem to be reacting the same and as expected to the addition of a weight in the trunk
Now, what is interesting is the following
a) Prior to taking the car in, and as part of my decision making about changing the rears, I measured the ride heights all around. The right rear was exactly to spec. The left rear was 2cm below. All struts and springs are original. So I interpreted that the left rear springs were failing while the right rear were fine.
But, it seems that my car is 2cm lower on the left rear all the time, and my 70k rear original Ford struts and springs were fine all along.
b) Prior to taking the car in, the front right was also at the exact correct ride height, while the front left was below by a cm or so. Now, the front left is about half a cm below the height of the front right, and perhaps that is related to the rear left?
Overall though, handling and ride have improved. The car had begun to pull left, due to the failing front struts, and that problem has gone.
The front sits higher with the Monroe quickstruts by about 1.5cm compared to OEM
/ official ride height specs.
The rear seems to be the same although I have this weird 2cm difference between left and right.
Thoughts about what could be causing this height difference in the back? Would an alignment solve the issue?
