why don't car makerrs standardise car parts?
why can't car makerrs standardise car parts?
Consider clutches. surely a clutch serves the same prupose in all car and should only differ in diameter in relation to engine power. So car makers
need to dsign the gearbox input shaft to be same diameter and the same number of splines so only 3 or 4 different diameter clutches would be
needed.
Spark plugs - two sizes, maye 8 or so temp ratings.
Wheels - one standard PCD and cetral hole for 3,4,5, and 6 dstud mountings.
Brakes - like clutches, are sized according to car wieght/power so again the calipers/discs need to be limit to maye 6 or so sizes.
Oil filters - all use same size thread and then need to be maybe sizes in 2 diameters.
why oh why does ever car manufaturere need to be different

I would have thought it was obvious,
So they can make more money out of us by selling parts that only they make

Some people are worried about the difference between right and wrong. I'm worried about the difference between wrong and fun.

AH HA but at least the bean tins are standardized (Is that a real word)
Seriously it'd be nice if your idea on std parts could become reality but as always we live in a less than perfect world.

Basically becuase its a free market. Manufacturers either make themselves for buy off the shelf from OEMs.
With OEMs competing on style/design/price and having copyright/patents on certain features there will be natural variations.
Designers improve engine designs, have constraints over space e.t.c which sometimes results in new OEM part designs.
The problem these days is as well as advancing design and sharing components accross manfactureres there are special variants and a whole load of old
cars still out there.

If you standardise the PCD's it would have to be a big enough PCD for the largest 6 stud hubs
It would make my 3 stud 106 hubs a little big and heavy if they had to be the same PCD as a landrover or a Hummer

Everything will be standard soon - it'll all be VW or Ford before long

If you want to standardise something, why not the turn indicators control? Either on the left or on the right.
If you see my windshield wipers going on a dry day you'll know I'm in the G/Fs car and I'm turning right.
C'mon Brussels, where are you ?

You could standardise so many things if you wanted to but there's no real cost advantage (to the VM) in doing so. So what if you have a 100mm
PCD and someone else has 4". You make your 100000 wheels per year and no-one else has the same so swapping would save nothing, so long as all
your 4 stud wheels are the same.
I work for a tier 1 supplier and we'd be more than happy to supply the same size parts to everyone. They tell us to make one "this
size" and we do. The cost of redesigning the car to fit the part is more than the tooling change to make the part fit the car.
If I were setting up my own car company, I would choose as many standard parts as I could find, but I can do this because I'm starting from
scratch, so my hub bearings and steering rack and brake calipers etc would just so happen to be the same as someone elses.

I used to flash the screenwash when I first swapped cars, doesn't it come as a surprise
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Those are probably the least likely to be the survivors! Toyota and Renault/Nissan maybe.
In reality, there are a lot of standard components across cars, but you won't find out from the manufacturers - these are items which they buy
in and the whole industry gains from economies of scale. I used to work for a bearing manufacturer and in the past there were only a few different
part numbers used for car wheel bearings. Things have changed a lot now though, the manufacturers are fitting bespoke parts which make it more likely
they will get the replacement business through their own parts division and this can be very profitable for them. If you know where to look you
don't usually have to go down this route though, whatever the manufacturer may tell you.
