I recently purchased a 1998 LC ~ 111000 miles. I’ve gone thru a priority list I made and used this forum along with Toyota maintenance recommendations to begin the quest to bringing this well made, well kept and well loved exceptional vehicle back to top condition.
I’ve been monitoring this forum for information and I find it refreshing so many owners of the Land Cruiser’s take such meticulous care keeping their vehicle in top mechanical condition and thought someone may have an idea on an issue with a rattle in the steering column I have, but haven’t located the source ~ yet. With the engine off I have laid on the floor beneath the column to listen and observe and while moving the steering wheel from side to side there is a auditable knock as though the small universal joint has the slightest amount of play to allow a solid knock by turning the steering wheel both directions just before it gets firm. (There no excess play) Nothing appears loose in the column unit or it attachment to the inside dash supports. All steering line components seem to be solid without the slightest amount of play. The entire unit looks to be in near new not new condition. My particular model has pivoting allowed for height control for the driver, but doesn’t have telescope designed into the column as some models offer. I’m thinking my sound is from below the firewall and because of such a solid unit it appears auditable in the column within the cabin. One other Problem I have is, I have a broken spine and removing the skid plate to gain access is a monumental job for me just to find the source of the rattle if it’s over looked under the dash. I’d prefer not to be searching the wrong direction if I’m over looking the problem and it’s right in front of my face to begin with. So, I thought you guy’s may have had a similar noise and can point me directly to the little gremlin per say. Allow me to add, everything directly related to the steering and suspension is in well-maintained condition from what I can observe under the vehicle with out skid plate removal. I had a small amount of oil on my driver’s side shock and I replace them all with OEM.
To answer some questions that may be asked allow me to give a short summery of work and information about my LC. I believe my particular Land Cruiser was very well taken care of by 3 previous owners.
During my initial inspection before purchasing I came to the conclusion great care had been taken with maintenance over the course of vehicles life. All fluids were clean, all external belts and hoses were in near new condition. I found nothing to indicate wear except the mileage recorded on the speedometer. The Car-fax for this vehicle was clean. There were no maintenance records supplied from the sales company although I found through other sources my LC had been kept up-to date to 55000 miles with maintenance and then a complete brake job and bearings was performed at 74000 miles less than one year from my purchase date by a local Toyota dealer. The sales company put new tires (Goodyear Wrangler AT/S LT265/75R16) and aluminum wheels on before the sale. I had the timing belt, water pump, front oil seal and serpentine belt replaced along with complete OME shock front and back from a local competent trusted mechanic the week after I purchased my LC.
The timing-belt showed normal wear but without any cracks. There were stains showing a minute size leak beginning in the water pump. I changed the spark plugs to NGK Laser Iridium IFR6T11-4589, which took me an entire day because of my spine. I was pleased with the old plugs condition although they look to be original Denso Iridium SK20R11.
My resources used to identify steering components are Max Ellery’s Toyota LC 1990 – 2002,Chilton repair Manual Toyota 1997-00, along with parts illustration Steering Column from Parts Cheap Toyota.com.
This is my first thread and I believe intelligent engineering and problem solving is a collective source of ideas from many people. Any ideas or suggestions will be deeply appreciated?
 
Wow, you are very concise and damn it hurts to hear you broke your spine. I hope she was worth it ( :

In terms of the rattle, that is the first I have heard i.e. steering rattle. But I will say that it is very very easy to think that a noise is coming form one location and it is actually coming from another. A vibration usually involves a running/moving auto i.e. vibration created by mechanics of X or Y in motion. I do not think that the sound you hear has anything to do with your steering wheel or linkage. Typical points of vibration have been seen at the heat shield for the cat, the upper dash (DS) and the front end when a shock or bushing is shot. The heat shield on these 100's always break/crack for some reason and most have experienced the upper dash rattle on cold starts and prior to reaching 15mph.
 
So the audible knock you describe with the engine off, this is not the same rattle you are trying to track down correct? You can reproduce the sound with the engine off?

and welcome to the board as well :)
 
It might be a bad/loose steering joint (?). Try PM'ing fj55-100 about it, I remember he was talking about this once as a semi-common problem on 100's. Sounds identical to what he was describing.

good luck
 
Thanks for direction

Hey thanks for the feed back relating to my Steering Column noise. It appears I did a poor and confusing job describing the noise in my steering column. I mention the engine being turned off because it’s not engine, exhaust, or dash related. It’s a mechanical noise from the steering column.
If I take hold of the main shaft under the column with my hand and move it from side to side I get, what I described as knock within the upper Steering column just below the Steering Wheel. Same as when I take hold of the steering wheel and turn from side to side. But when I drive at any speed down a dirt and bumpy road it sounds like a rattle because it’s multiplied by vibration up thru the steering components from a ruff or washboard surface. I believe FirstToy pointed me in the right direction and I’ve found a lot of information using search with bad/loose steering joint. Thanks for the welcome and Thanks for the help.
