The rear springs are done in the same manner as the front
springs, so I won't go into detail on them. We used the spring compressors
to dismount the Tera 2T springs and also to install the 4" Procomp
coils. So as to get the maximum axle droop for easy coil removal, we also
disconnected the rear sway bar links and the track bar. This let the axle
droop as much as it could since we had the frame up on the jack stands.
Here is a picture of Michael, a local Jeeper that lives on the other side of the valley. Michael and I met via one of the internet forums (Jeeps Unlimited) or maybe it was the local on-line club( Arizona Virtual Jeep Club). Which ever it was, Michael showed up to help Alan and I spin wrenches. I got this one of him under the rear axle taking the sway bar links off.
In the above picture, you can see the 4" Procomp spring on
the left and the Tera 2" spring on the right. (and the front tire of
my wife's XJ too)
Since I was going for good height balance between the front and
rear of the Jeep, I decided to use two different sized spacers. I had been
running the Tera spacers shown in the above picture. These are the
.75" spacers that Tera sells and will keep your Tera springs in
warrantee. Specifically, they are 1.25" tall, but are called a
.75" spacer since you would normally pull the .5" rubber isolator
(noise deadening pad) at the top of the spring perch before you install
them. I am running the Tera spacers with the front springs (with the
factory isolator in place) and the Brand X spacer with the rear spring.
The Brand X spacer measures 1.75", or .5" taller than the Tera.
Since I carry a fairly good load in the rear (custom
storage box) and when doing an over nighter (jerry
can rack), I decided to give the rear just an extra bit of help by using
a taller spacer. I removed the Tera bump stop and installed the RE bump
stop in its place. I think I might be putting the Tera bump back back in
(in addition to the RE) since I am going to over compress my rear springs with
my current set up.
As you can see in this picture, the 2" RE bump stop
extension just protrudes through the 1.75" spacer. As I mentioned
above, I think I am going to add the Tera extension back in. If I don't do
that, I'll get longer bump stop and insert that.
Here is a picture of the rear spring in place. You can see those new RE control arms in the picture as well. I removed the shock the following day (while finishing up the little details) when I discovered that even with the TJ sitting on the tires, the shock was about 2" too short from reaching the lower mount.
March 25, 2001 - I installed a pair of Daystar bump stops today. I stopped the by local 4x4 shop yesterday and actually remember to get them while picking up a new set of Bestop seat covers.
The Daystar bump stop is 2" longer than the factory stop, as you can see in the picture above. I found that the composition of the Daystar bump stop was much harder than the factory stop. As such, pushing it into the bump stop cup was....well, I found it impossible. My final solution was to grind three flat spots on the stop, at 120 degree intervals. I took a little of the material off several times and continued until I was able to forcibly insert the bump stop into the retainer cup. Actually, I used a pry bar to persuade it to go in. This way, there won't be any problems with it falling out on its own. So, now my 4" spring has a 2" bump stop in it. The RE bump stop is simply compensating for the 2" spacer.
