Posted: Fri Apr 14, 2017 22:07 Post subject: Pulling to left, no obvious cause, any ideas? LJ79 |
|
|
Car pulls slightly to the left. Braking or not makes no difference. It just wants to sit with the wheel slightly turned to the left, then it's happy.
Replaced 4 tyres in November. Can't say I noticed anything untoward then.
Recently swapped tyres across just to eliminate any bad tyre. No difference.
Took it to a geo place. Told me geo is spot on, may be tyres. He even told me that since the only adjustment is toe, even if it were out, I would not get a consistent tug to the left.
I also engaged both freewheel hubs, on the off chance that perhaps the LHS one was not disengaging, but no difference, so eliminated too.
I don't really get this. Hate it when I can't get to the bottom of things, when all seems fine, but evidently is not.
Frustrated. Tomorrow may try replacing front tyres, have an extra pair. Any ideas? |

Have you jacked up both front wheels to see if one brake calyper is binding? |

Hi yes and actually replaced brake pads (not for reasons related to issue) a couple of weeks back, no difference.... ugh |

re you driving on roads with serious camber surface? If this is possible, find a suitable road and drive on right to see if it makes any difference.

Not camber related, does it everywhere. Yesterday replaced both front tyres - no change. Also measured wheelbase side to side - spot on. Put it on shaker plates (? - the MOT suspension test devices) and apart from a very minimal (to the point of insignificance, way off a fail) play in a kingpin bearing, nothing. Not to mention that I had a lot more play in them prior to replacement some years back and it never pulled anyway.
I have not tested one thing, lifting the front and starting the engine, wonder whether it is possible for the steering box to be "pushing" to one side? But I doubt it, as it basically just finds its position and sits there, furthermore I also centred the box's movement (there was uneven lock) i.e. effectively changing the box's "straight ahead" and no change at all.
Very frustrating. |

Have you modified it in any way?

Hi Roger, no, all "stock", including ride height, etc.
One Q - the steering damper - I take it that is just a damper, no possibility of it pushing or pulling in any way? |

It's a damper, nothing more.
Have you checked the rear brakes? Have you checked the front wheel bearings?
Without actually driving the motor, we are now scratching for ideas.
"When you have eliminated the impossible, whatever remains, however improbable, must be the truth". Now who said that?

is there any sign that one or other of the axle knuckle/diff oil seals have failed? zap a laser thermometer onto the knuckles/axle ends/hubs to see if the left side is getting hotter than the right?
dunno |

Right, so the saga is ongoing, but a Lidl protractor, it seems, is more useful than a bells and whistles geo place.
Long story short, using the protractor I discovered that either one front wheel is splayed in, or the other is splayed out (camber).
I need to know which it is, saves taking apart both sides.
Does anyone have the geo settings (full, not just toe) for the 70 series?
Or, failing that, whether there is supposed to be any camber at all at the front, i.e. any setting other than 90 degrees to road surface? |

Wheel bearings. My LJ78 was doing the same thing...after alignment, brake pad replacement and associated debacle with hubs, etc, I replaced wheel bearings and voila!

I rebuilt both knuckles on my 73 last year. Camber is governed by use of shims between knuckle bearing pin where they're attached to top and bottom of ball joint at end of axle... beneath the plates top and bottom with 4 bolts. Only way i can think that camber would change is:
bolts come loose
Pins are worn
Or that the wrong shims were fitted ... but this woulnt explain camber changing over time
I wouldnt disagree with last post but imho the bearing would have to be seriously knackered and making a racket before it started to effect handling.
Any progress recently? |

The shims on the steering knuckle are there to adjust the pre-load on the knuckle bearings. It is normal practice to equalise the shim thickness top and bottom to maintain a central position of the knuckle onto the axle so that the grease seal can be correctly fitted.

Ah... got that wrong then. Is there any adjustability in the camber then?
cheers |

Sorry no, it's all part of the welded up structure of the axle casing.
