Was ist Spreizung? (Wheel alignment)

Hi,

I'm looking for help translating "Spreizung" in the context of Wheel alignment secondary angles

My Discovery's steering wheel turns ever so slightly to the left at the end of braking. I don't feel that this is unsafe to drive, and I suspect this would be an MOT advisory in the UK, but I have an MFK appointment in a month so I probably need to fix it.

Earlier this year I replaced tie rods and tie rod ends and then had the steering alignment set (attached). You can see the guy highlighted a section, "Spreizung" under secondary angles in the print out of results. He also incorrectly told me my car has been in a crash! This is not true, but I need to run this past some land rover people on another forum to determine the scope of work I need to so, hopefully avoiding lower front wishbone replacement....

List of wheel alignment secondary angle adjustments is here:

https://en.wikipedia.org/wiki/Wheel_alignment

Thanks,


Andy

King pin inclination.

https://books.google.ch/books?id=sQI...gnment&f=false

According to your data sheet, both left and right are off (in the same direction, both are leaning more left than they should be, 1 degree LH, 0.8 degree RH).

Why didn't they correct it?

As the tollerance is 0 for this, I would imaging that it is not possible to adjust, and thus something is bent, which is why the guy told you it had been in an accident.

As you are not the original owner, how do you know this for a fact?

Re: Was ist Spreizung? (Wheel alignment)

Unless you are the first owner how can you be so sure the vehicle has never had to endure a "bang"

Did it already do this before the repairs, or did it start right after this (which means the replacement has been done either wrong, or with wrong parts)

As for telling what causes your wheels to have the wrong angle when steered is impossible on a forum without actually seeing the car.

Again, as the min and max allowed values are the same, there is 0 tollerance, and thus the system is not adjustable for this value, i.e. something is bent.

Yes darling, but we do not know what would be bent, do we?

Also we do not know yet if it was there already before the replacement or if it might be due to a wrong replacement, or if this always has been the case since OP owned the car, or if it started after he borrowed it out one day to a friend.

I know what you are thinking, you naughty girl, but that one isn't documented, https://de.wikipedia.org/wiki/Spreizung

I have had this car on a ramp enough times, there is no accident damage. Thanks for the translation! (both of them...)

Re: Was ist Spreizung? (Wheel alignment)

It would be an odd accident to bend both sides, or the beam... unless you dropped the car from a great height.

From the numbers the alignment machine spits out sommat ain't right.

Bent flanges between the diff and the steering end?

Re: Was ist Spreizung? (Wheel alignment)

Just in case you are interested..... consensus on Land Rover forum was that I do need to replace the front lower wishbones "lower arms" which will have 2 new bushes and a ball joint and that should hopefully solve my problem. I should get them this week and that will be a challenge for Saturday.
