1978 Jeep CJ7 • 100,000 miles

Lucky, not electrical ! Seems it is just easy to flood out, whew,
now, when the weather breaks, test drive, maybe replace the front tires? To see why it on occaision pulls enough to suddenly jump to the next lane?

keep on with the great info and have a very merry christmas, i'll be sitting here watching tv and drinking hot chocolate ! Lol

hopefully i'll find a job for the new year ! ; )

Either you need a front end alignment or you have a loose suspension component like the tie rod ends or the lower ball joints are the most likely to be loose. This will come out in an alignment as it will not align with loose components. But, you will be stuck with the alignment shop fixing the suspension. If you want to find the loose part, jack up the front of the truck. Grab each wheel and grab the tire at top and bottom and push and pull on it. If it has play then the lower ball joint is most likely in need of replacement. Then grab the tire at the left and right sides. Push and pull to see if there is play. If there is it is most likely that the tie rod end needs to be replaced. You can replace the ball joints with a special tool that Auto Zone or advance Auto gives out on a loaner basis. To do the tie rods the most importan thing is to keep the ditance that the tie rod is connected to the steering knuckle the same. You can count threads and mesuire from several points. It will still handle funny as it needs an alignment after you do this because the measuremnts are less than a degree. So, be careful driving it to alignment shop after you replace components. If there is anything else loose, it will be not so loose that it won't align as they will try to sell you the repair. So keep the loose components in mind that they tell you about s you will need to replace them in the future and get another alignment. You should rotate and balnce tires every couple of months ofr6000 miles and get an alignment every other time you do that. So, it is not a loss.


DOES THIS PUPPY LUNGE INTO THE OTHER LANE

AFTER FEMALES?

RESULT OF USING THE BRAKES?

IN THE STEERING?

IF YOU THINK IT'S IN THE STEERING OR OTHER

TURN THE WHEEL TO THE RIGHT GENTLY--ONLY HARD ENOUGH TO REMOVE THE SLACK (NOT MOVE THE WHEELS)

HOLD IT THERE AND MARK 12 O'CLOCK WITH EZ TO SEE TAPE

THEN TAKE OUT THE SLACK/SLOP TURNING TO THE LEFT---STOP BEFORE THE WHEELS MOVE---THEN MARK 12 O'CLOCK ONCE MORE

SEND ME THAT PIC AND A PIC OF ONE SIDE OF YOUR JEEP

JUST WANNA SEE HOW YOU ARE SET UP

THIS WAS MY SLOP (TAKES 2 PICS TO SHOW IT)--PRIOR TO REPLACING MY STEERING GEAR---MY OTHER STEERING COMPONENTS WERE FINE----I WILL ADDRESS ALL OF THE OTHER STEERING STUFF WHEN YOU RESPOND

I WANT YOU TO GET YOUR PAL (WANNA BE) TO MOVE YOUR STEERING WHEEL LEFT AND RIGHT ---JUST MOVING THE WHEELS AT EITHER END OF TRAVEL

LOOK AT ALL OF THE LINKAGES AND TIE ROD ENDS WHILE IT'S MOVING L&R IS THERE SLOP IN ANY OF THE JOINTS? EVEN A LITTLE BIT IS TOO MUCH!

WHILE UP FRONT--HAVE PAL TURN A BIT HARDER ON EITHER END OF STEERING TRAVEL---DOES YOUR LEFT FRAME RAIL FLEX?...IN OTHER WORDS DOES THE GEAR SIT STILL AND ONLY THE STEERING MOVES---OR IS THE GEARBOX MOVING TOO?

YOU WILL SEE HOW I "HOMEMADE" A STEERING GEAR BRACE---YOU CAN BUY 'EM FOR MAYBE $75+. ALL I DID WAS USE ANGLE IRON AND MODIFIED THE ENDS TO BOLT ONTO THE GEAR BOX AND THE OTHER END IS WELDED TO MY FRONT RECEIVER HITCH

NEXT LOOK UNDER THE HEED AT 2 PLACES---OBVIOUS IS THE 'U'JOINT IN THE SHAFT (A LITTLE SLACK THERE IS FINE, IF IT'S FLOPPY IT SHOULD BE REPLACED

THE 2ND PLACE IS HARDER TO SEE, IT SORTA A TELESCOPING JOINT, WHERE THE SHAFT HOOKS TO THE STEERING GEAR (IT SHOULD/ DID HAVE A RUBBER BOOT ON IT--IT'S A 2 PIECE PART---THERE SHOULD BE NO SLOP IN THE PIECES (NUMBER 3 IN IN THIS LINK)

I have checked all the joints, twice, lol, I may not quite have the strength anymore to move the tire around, checked out the joints also, they are tight best I can tell. It may just be the alignment, as for years, one of my chargers did a similAR thing. Till I got my alignment tools on it ! ; )

I might get to it sunday? Possibly tomorrow? I have to get ready to do a photo shoot for a friend who is renewing his vows tomorrow, so I have to get the general cleaned out some, lol
it prob has the same slack you have in the pics?
It just shoots over, no input from steering/brakes ! Scary, the steering shaft bearing was shot, we replaced that, I probably won't get out to check everything for tightness till jan?

IF POSSIBLE, TAKE IT TO A "BEEN AROUND A WHILE" REPUTABLE ALIGNMENT SHOP---NOT THE "CHEAPEST" ONE AROUND

EXPLAIN EXACTLY WHAT IT IS DOING TO THEM

IT MAY BE A "CASTER" ISSUE

I HAD A FRIEND WITH A '72 CJ 5, TO KEEP IT IN HIS LANE, HE HAD TO STAY ON TOP OF IT CONSTANTLY. YOU COULD NOT "CRUISE" "HANDS OFF" NOT EVEN FOR A SECOND, WITHOUT IT WANDERING

I DON'T KNOW EXACTLY WHAT CAUSED IT (UNLESS IT WERE SOME MAJOR 'H. ELL DAMAGING' OFF-ROADING, FROM A PREVIOUS OWNER). IT WAS NOT OBVIOUS TO THE NAKED EYE, THEY SAID HIS FRONT SPRINGS WERE "TORQUED". THEY SAID EITHER REPLACE THE SPRINGS OR SHIM THE AXLE AS TO BRING THE CASTER BACK TO CORRECT SPECS (ROTATE THE TOP OF THE AXLE REARWARD, OR CW, VIEWED FROM THE DRIVERS WHEEL). HE CHOSE THE SHIMMING.

Since I got my alignment tools, I have been doing my own, till I can get $$, it has done very good, haven't burned up any front tires anymore.
The caster is always a wild thing, it causes the sudden'jumps', because the wheel moves like a front wheels of a shopping cart flopping back and forth !

I won't be able to get that deep untill I clear the cement pad out back.

JUST JUMP BACK ON THIS POST WHEN YOU GET 'ER FIGGERED OUT

LET ME KNOW WHAT YOU FIND

IF YOU SHIM SOME CASTER IN (UNDER THE FRONT OF THE AXLE PADS, ON TOP OF THE LEAF SPRING) REMEMBER THE GEOMETRY CHANGES AND YOU'RE GONNA HAVE TO RE-DO "TOE"

SEE YOU SOON
