What year Durango for the gear box? Starting to get sector shaft movement.

 

Greetings ... Im new to this site and looking around i saw a post that you had made and then saw that you also have a 90 cherokee, as do i. Did you delete the closed renix system or is it still the same as orginal? Did you delte the heater control valve? I learning and reading a lot of information and at times its overwhelming...but i still try to learn. Thanks

 

GREETINGS ... I'n new to this site and saw that you too have a '90 cherokee renix. Did you leave it orginal as to the renix closed system? Did you delete the heater control valve? many questions i have. thanks

 

this in awesome thread! lets keep this updated. i already have the labaron hood vents and next i wanna do the injector swap.

 

I'm curious why there isn't the addition of the "A340" transmission from Toyota... It's used in trucks, Lexus, Supras.... even the TT supras when its beefed up a bit.

 

[QUOTE=RedZeppelinXJ;663678]Hey guys for the sake of everyone doing budget junkyard builds I was wondering what parts from other vehicles will fit an XJ with little or no modification that will help the performance/offroad capabilities of the XJ....feel free to post your mods and links to build threads if you have them.....this thread is to help new guys on a budget get started

***note that these are not all bolt in mods, but can be done by most who are mechanically inclined with the right tools

Here is the latest re-cap of what we have found:

Suspension & Lift:
1. ZJ V8 Upcountry Coils = 1-1.5" lift
2. F-150/Bronco Coils ('70s-ish) = 4-4.5" lift
3. S10 (P/U or Blazer) leaf packs (cut eyes off S10 main and bolt pack under XJ main) = 3-4" lift (may require use of degree shims)
4. Dakota Bastard Pack (do same as with S10 pack) = ~4" lift
5. JK shocks = slight mod to fit 2-4" lift (some dispute)
6. MJ Shackles = 1/2" lift
7. Camaro Spring Isolators = 1.5" lift
8. Full size Blazer Bastard Pack (do same as S10 pack) = 4-4.5" lift (may require use of shims) may be stiffer than S10 leafs
9. ZJ spring isolators = stronger, metal core, can be stacked
10. GM fullsize pickup shackles ('95-99) = 1.5" lift, better shackle angle
11. Thunderbird Front Coils ('83-97) = 3-4" lift (varies in lift and softness by year and trim package), will need top plate from strut too
12. Any 2.5" wide leaf spring can be used between to make a bastard pack (they may differ in stiffness and lift)
13. S10 Shocks (Rear only) = good for the lift you will get when you do a bastard pack
14. TJ Lift Coils (front only) = provide 1" less lift on an XJ than on a TJ

Brakes:
1. WJ brake booster
2. WJ Master Cylinder
3. YJ Brake Lines = 3-4" longer
4. Dodge Ram Van Brake Lines = 10-12" longer (for big lifts)
5. WJ Rotors/Calipers = bigger brakes and more stopping power (will fit 15" rims)
6. ZJ brake booster, master cylinder, proportioning valve = may need for disc conversion
7. XJ '95+ brake booster and master cylinder = dual diaphragm
8. Dakota Rear Softlines ('95-00) = 6" longer
9. GM C/K1500 Front Softlines ('90-95) = 6" longer
10. KJ disc brake set-ups can be used for a conversion on your XJ axle

Axles:
1. Ford 8.8 inch ('97+) = need spring & shock mounts (3.55, 3.73, or 4.10, maybe LSD, Disc Brakes)
2. XJ I-4 & some V6 = may have 3.73, 4.10, or 4.56 gears may have vacuum discos
3. XJ C8.25 ('97+) = bolt in and upgrades to 29 spline (strength comparable to D44)
4. XJ D44 = found in some but not all '87-'89 XJ's with Towing Package
5. Lincoln Lockers = welded spider gears, operates like a spool, must be a GOOD welder
6. MJ D44 = need new spring perches and shock mounts
7. XJ D30 = ('95-'99) non-disconnect, larger u-joints, high pinion, bolt in
8. Homebrew posi-locks for '84-90 vacuum disconnect D30s, eliminates vacuum actuation (use search function)

Front End & Steering:
1. ZJ V8 Tierods = beefier & bolt in
2. WJ Knuckles/Tierods/Draglinks = beefier and crossover steering
3. Durango Steering Box = beefier
4. 350 or 351 Power Steering Pump = helps with oversize tires (requires welding)
5. WJ LCA's = more tire clearance (some grinding required)
6. ZJ pitman arm = 1 inch drop over stock
7. WJ rear LCA's = replace XJ front LCA's, 2" longer to accommodate a lift, some grinding required
8. WJ power steering pump (fits '96+, plug return hole, and use XJ pulley)
9. V8 ZJ front sway-bar
10. JK rear UCA = use as XJ LCA, its about 1-2" longer

Engine/Transmission/T-case:
1. Newer XJ intakes (may require some modification)
2. Mustang 5.0 Injectors = near bolt in (have 4 holes instead of 1, more fuel, better spray)
3. ZJ V8 alternator = more power to run accessories (some grinding required) 136A (for 1991 and newer XJ's).
4. Ford Electric Fan ('90-95 3.8L Taurus, '87-93 5.0L Mustang) = replaces mechanical fan, more cooling (8C607)
5. 2.5L Dakota Alternator = bolt in, upgrades to 117A
6. Dodge Neon Injectors = better throttle response
7. '94+ V6 Dakota AX-15 = bolt in (but must use XJ bellhousing)
8. ZJ and WJ stock tranny coolers with stacked plates (even an upgrade for us with the stock fin style)
9. 5spd crossmembers give 3/4 inch t-case drop on autos with no loss in ground clearance
10. Hoodvents (i.e. Lebaron, Laser, Turbo Thunderbird etc.) = help keep ur 4.0 cool at low speeds
11. You can convert the closed system to open without replacing your radiator by using the fill cap from a 4.7 durango or dakota, cutting it into your upper hose, and replace your bottle with an MJ overflow tank or any that fit. Then cap off or eliminate the T'ed lines in the heater core.
12. Homebrew Slip Yoke Eliminator (use search function)


Body/Interior/Armor:
1. 97+ mirrors are direct bolt in to older XJ's and allow you to fold them in on tight trails.
2. MJ/2 Door XJ Bucket seats = tilt forward, bolt in
3. ZJ gas tank skid = can be modified to fit 97+
4. GM power antennas replace your broken XJ's with little modification
5. XJ '97+ doors onto older cherokees = one piece windows and better mirrors
6. XJ overhead console = most commonly found in '00-01 or higher trim level, provides space for switches etc.
7. '97+ center console = can be made to fit '96 and older, gives you cupholders!
8.'96-00 Ford Explorer hatch shocks = lift your hatch about 3" lower but are beef (ever see one that doesn't work?) need modification for '97+
9. OEM skid plates (Front, Tranny, T-case, gas tank, found on "up-country" package XJ's)
10. OEM swing-out tire carriers, get the bumper with it, found mainly on '84-'90 XJ's

I found a 2001 Grand Cherokee that has a new motor how difficult would it be to install it iny 1990 Cherokee thank you in advance

 

Great Info.

 

Ok, so I have a 03 liberty with the rear disc brakes and was considering swapping them to my 99 xj, is this a direct fit or does it need modifications?

 

8.25 yes, d35 i'm not sure.

 

Ok I'll have to check on the axle

 

2 questions, for the Zj coils was it the front or rear that are needed? and for the durango axles is the 2nd gen durango 9.25 the same width as the Xj rear and will it still bolt in?
