Propshaft U.Js replacement kit

[Blower]

I ditched the original 2 part prop for the more versatile( Rallye ) 3" Rocket to English single piece prop years ago

The front U.J is now showing signs of wear

ive done loads of digging into the replacement of these

It looks like a simple , UJ - 1300 , 27 x 74.6 swap from the GKN 18179

Motor sport web sites advertise them for 40 to 50 notes

Would i have to have the prop balanced again ?

[Graham]

no the prop should not need rebalencing because you are not making any material changes to the length/weight/wall thickness of the hollow section.

changed loads of U/Js over the years without issue

Would say you would be very unlucky if you had to, changed hundreds over the years and never had cause to have one re- balanced yet.
