    Shortening AK steering extension shaft

    Hello all,
    Hope all keeping ok in these times.
    I need to alter my steering extension shaft.
    Its very close to my headers, about 1mm from clutch master and 1mm from water pump housing the other end.
    Having a play tonight i could slide the shaft out of the bmw steering rack 100mm or so and it will still have 50mm plus inside the bmw steering spline. So could i shorten the length between the two ujs on the extension shaft...?
    I guess cut shaft between ujs, shorten and make a shaft to slide over each end and weld up...?

    Yes is the short answer. Chop a chunk out of the middle of the shaft, sleeve over the shaft, drill and plug weld either side, weld around the ends of the sleeve - probably overkill but better safe than sorry.

    Cheers

    PS - had to do similar to mine when I converted to EPAS

    I’ve Done this a couple times. Usually to allow set up in a lathe to machine the shaft down in diameter for more clearance past the wishbone/suspension area.

    Better off to cut the weld around the back of one of the ujs. Remove the shaft from the Uj then shorten the shaft, put shaft back in U.J and re weld.

    Or get a replacement/return to AK for it to be done if you don’t have access to a welder etc.

    Cheers all,
    It would give me a longer straight angle coming out of the steering rack.
    Btw the nut on the end of the bmw steering rack which sometimes catches some of your pedal boxes, is this suppised to be tightend once length is right or left to float in the spline...?
    I use a bearing bush on the shaft as it comes through the firewall and grub screwed to shaft...
    Regards
