hi there boys and girls, just wondering if any one has used these 25mm front tailshaft spacers before ??? And had success??.i have just installed a 6" lift in my truck and have noticed when i lock the hubs in and put it 4wd at about 80km when i back of the accelerator i get a spinning vibration feel and noise this only happens when hubs are locked. I have drop boxes and cross member has been notched correctly with plenty of clearance both tail shafts fully rebuilt. i have read on a few posts to use these tail shaft spacers but there is bugger all about any wins with them. I don't want gear box spacers i wanna test run these tail shaft spacers first any info would be great cheers
