REAR COIL SPRING ANGLE DUE TO LIFT KIT INSTALLS

Alec (ccbruin) asked me to take a look at the angle of the rear coil springs on his 2002 TJ as he didn't like the way the springs bowed out. He is running an after market 4" or so Skyjacker Lift kit. I looked at the springs as well as the possibility of cutting off and rewelding the upper mounts in a new location. The cost of doing that is a bit prohibitive due to the welds and accessibility to the inside of the frame rails, so I decided to do a little research into the problem. Here is the information I sent to him, including sources from a couple of different manufacturers who provide kits to correct the problem. Hope this helps people with the same issues.

My question, of course, is if the manufacturer's of the Jeep lift kits KNOW that the rear coil angle is going to be changed SO MUCH that it causes a PROBLEM, why not provide the necessary correction bracketry TO BEGIN WITH? Really...just how ******* simple a solution is that? This seems to be a problem with any of the lift kits for Jeeps (to some degree, increasing as the lift increases) that I looked up, no matter who made them. Most of the companies offered a 'correction kit' for an additional price. That, people, is just plain stupidity....

Doing a little digging this AM regarding the rear coil angle. I pulled up the first two links and didn't get much, but here they are anyway. The best pictures are in the second link, but the coils are straight. I then googled 'problems with coil spring angles, etc" and the first thing that cropped up was a rear coil spring angle correction kit from Rough Country.

And yet another fix for the same problem, but addressing relocating the top bracket:

The T&T Customs Coil Spring Relocation Brackets ($149)used:

And a similar one offered by Black Diamond ($109, but weld on) to address the same problem:

http://www.jeeptopdepot.com/productd...x?partID=42614

At any rate, Skyjacker and all the other companies should simply sell these parts in their lift kits to begin with as it is an recurring problem. If you decide to address the problem with one of the after market correction kits (and I am sure there are more than what I listed) keep in mind that a bolt on kit for $149 is probably going to equal a weld on kit for $109 by the time that the welding is done.

UPGRADING YOUR DANA 30?

Here is some information and links courtesy of Popsgarage (Jonathan):

Upgrading the Dana 30. I think they've gotten a bad rep because they've been abused by kids who have no skinny pedal control. And the stuff listed here is just a start. I've been doing research on this axle for 5 years in preparation for an SAS in the wife's '94 Chevy S-10 Blazer. Now mine by the way.

RCV axle shafts. Lifetime you break 'em, we replace 'em guarantee. Kinda like a set of Bobby Longfields.

Ballistic Fab. Using their XJ TJ Coil spring brackets in conjunction with their truss would strengthen the 30 pretty well.

Jeep Brake Line Trail Repair from ErrinJan:

Almost every Snow outing I've been on someone has torn off a Brake line including myself yesterday. Driving home with 1 front brake is hair raising at best.
Here's a part listed by Josh at S.F.F. Customs that makes for a cheap trail repair- Factory Chevy soft lines. They are about 25 inches long. And about 13-15 bucks at the parts store. Stock TJ brake lines are 18 inches.
Makes a nice upgrade or trail spare.

This brake line fits several different vehicles!

Wish I'd had one yesterday.

Here's a couple of options for the unit body stiffeners. I'm a bit partial to the RuffStuff ones just by virtue of design. They spread the weld load over a much greater area. The T&T ones are nice, just two pieces.

-------------------------------
KJ - Liberty - 2001 - ? (we miss the XJ...)

-------------------------------

FULL SIZE JEEPS
====================================
SJ - Wagoneers - 1963 - 1983
SJ - Grand Wagoneers - 1984 - 1991 (4 made in 1992, see #12 below)
SJ - Cherokees - 1974 - 1983
SJ - J series - 1963 - 1986
====================================
(no idea what the compass and patriot models are, nor do I care at this time...)
-------------------------------
TJ - Wrangler - 1997 - present
-------------------------------
VJ - the 2wd JEEPSTER - 1948 - 1950 (see #6 below)
-------------------------------

WJ - Grand Cherokee - 1999 - 2004 (completely new design, different from the ZJ)
the WJ is a superb jeep - avoid the 4.0L, it uses the same weak trans as the ZJ
and will not get that much better mileage than the 4.7L V8 which is a superb engine!)
WK - Grand Cherokee - 2005 - present (completely new design, different from the WJ)
(note: the WK has independent front suspension, less visibility, and what's up
with no "J" in the designator??? - it's a horrible change from the WJ.)
-------------------------------

XJ - Cherokees - 1984 - 2001 -- THIS WAS the BEST all around Jeep ever!!!
XJ - Wagoneers - 1984 - 1992 (see #3 below)
-------------------------------
YJ - Wrangler - 1987-1995 (see #4 below)
-------------------------------
ZJ - Grand Cherokee - 1993 - 1998 (this is the GC with the Park/Reverse issue!)

john's vehicle history

<<< CORRECTIONS and additional Notes (input from Paul Weitlauf) >>>

1) Actually CJ stands for CiviJeep. It was trademarked by Willys-Overland
but never actually used. The model NAME for the CJ was 'Universal' until
1972, when it was dropped and the bobtailed Jeeps were just known by their
CJ-5, 6, 7, 8 & 10 designations.
1945 was the first production year for the CJ-2 Agri-Jeep (12 made).

2) DJ stands for Dispatch Jeep, not delivery. First introduced in 1952
as the DJ-3A, I'll have to check into the last year of formal DJ's.
Later Postal Jeeps are commonly called DJ's, but I recently found out,
at least in later years, this is not completely correct, they had D- #'s.
According to "JEEP - The 50 year history" it appears '73 was the last
year for non-governmental DJ's.

3) XJ Wagoneer's last year was '92. In '93 the XJ Wagoneer equal was
called the Briarwood

4) YJ's were made from '87-'95! There was NO '96 model Wrangler at all!!!

5) ZJ Grand Wagoneer '93 - ? Not sure, but I THINK this was only made in '93.
(editor: regardless of the year, it doesn't qualify for recongition, it
is NOT a "Grand Wagoneer", it's more a Chrysler mini-van with wallpaper...

6) VJ Jeepster '48-'50 (2WD only) :(

7) FC Forward Control Trucks Nov'56 ('57 model?) -'66

8) C-101 Jeepster Commando '67-'73 (Jeepster part of the name was dropped
in '72, so '72 & '73's are just Commandos.)
(editor: many of these shared parts with the CJ-6)

9) 4XX & 6XX Willys Wagons & P/U's '46-'65 for Wagons, '48-'65

10) This only lists the Civilian models, less the little Jeep van... not sure
what these were called and there's not much written on them.

11) The list for military models is almost as long.
(Quad, MA, MB, MC/M-38, MD/M-38A1, etc....)

12) There were four Grand Wagoneers made in 1992, although the last official
year was 1991. The very last FSJ is in the National Auto Museum in
Reno, Nevada. I've visited with it... touched it... photographed it...

CJ7 Ground Up Restoration Project. This is very well documented and, because it is a Jeep, almost everything this guy has done to this Jeep crosses over for other Jeeps. Everything was done to this rig, and the article is very well organized and well written. A great reference whether you need wiring diagrams or tips on how to restore vinyl.
