Hi guys i was able to shorten my h145 by 20mm overall (10mm either side)

Axles hit the spider gear cross shaft so i had to cut the end a few mm. Its roughly 4mm less spline engagement on the diff but with an a12 i think it should be ok

If i ever find a spare h145 diff i plan to cut the spline section on the side gears and weld it onto my diff side gears just to increase its length and give it more engagement.

And yes the one issue is the brake lines and nipples arr quite close to the spring plate but it seems fine.

Handbrake cable had enough adjustment in it to take the difference luckily.

Took the axles out and it seems there is about 6mm unused spline.

I might shorten it 6mm or 10mm each side, it isnt much but should help abit with tyre to fender clearence.

I will have to cut the end of the axle by 6mm as it hits the spider gear cross shaft.

I could go in 10mm but then it will be engaging 4mm less on the spline.

Would this be an issue for a a12 engine? I dont think 4mm less should cause any problem consodering the a12 dosnt make much torque.


Also what is the best method to shorten the diff? The end where the axle bolts and bearing seats seems to be sitting inside the inside diameter of the main tube and welded on.

I was thinking to cut the weld knock the end of take of 10mm and weld it back on

Anyone see a problem with this?

Has anyone shortened a stock h145 in a 120y?

I wonder if there is any excess spline on the axles even 10mm on either sode would help fit neg offset wheels.

Just wandering what spring length would be best suited when converting struts to coilovers.

Il be using 4 inch shorter vw golf struts.

The two options in spring lengths are 180mm and 240mm both 4.5kg (250lbs)

Im thinking 240mm will put the adjustable sleeves in a better spot (lower on the tube)?

Thanks

Good to hear he is fine!

Wandering the same.

Hope all is well

What does the internal of the strut measure?

They dont fit?
Is 38.1mm too big?

Hi

So i called up kyb head office and confirmed the part numbers

Part number: 361005 is a american part number

Part number: 363001 is for australia.

They both share same specs with the outer diameters being 38.1mm so it should fit inside a 45mm strut.

I will update the wiki with the part number to make it easier for people in the future.

I think i have found a part number for vw golf strut inserts for kyb.

From what i can gather the part number used to be kyb 361005 but i called up a auto parts place an that part number dosnt exist.

So i got him to look up a 1975 golf with the 1.6l engine and the part number that came up was kyb 363001

Can anyone confirm if that is the same part just new part number?

It seems available through auto part shops.
