PAH Donating Members 361 Member For: 15y 11m 22d Gender: Male Posted 08/03/19 04:01 AM Share Posted 08/03/19 04:01 AM Guys, My 2008 XR6T is making a bit of a hummy noise on cruise at about 110kmh. I can rule out the tailshaft. The next suspects on my hit list are the half shaft axles to the rear wheels. Should the OEM factory axles last longer than 10 years / 130k kms? The factory axles have been OK for the first 10 years so I suspect that they should be OK for the next 10 years. I'm looking at around $2100 for new factory axles plus fitting and $3000 for Heavy Duty axles. Has anybody found a supplier of quality FG XR6T axles at a better price? Another worry is my Eddie-the-Expert backyard diagnostics. I'm chasing a hummy noise at 110kmh on cruise on uphill runs. The noise disappears when coasting downhill. If I add the axles to the tailshaft shotgun list, what's next when chasing (assumed) transmission noise? PAH Link to comment Share on other sites More sharing options...

I'm thinking its the diff but it could be as simple as exhaust touching or stuffed diff bush's. Get some one to drive while you sit in the back & try to zero in on where the noise is comimg from Edited 08/03/19 08:38 AM by 4321 Link to comment Share on other sites More sharing options...

The Repco axles last as long as the factory Ford parts? I've been reading another thread on the forum and I picked up that Pedders sells 700HP axles. Does anybody have any info on these? I'll guess that they're heaps more than $200 each. Any feedback from anybody on the Pedders axles? I also found the AADI web page. Has anybody tried the AADI axles and if so any feedback? PAH.

Looks like its in the USA. Correct? I just picked up that Repco have a 25% discount on XR6T driveshafts but the sale ends Sunday 10th March 2019. If anybody has any negative feedback about these shafts please let me know QUICKLY. https://www.repco.com.au/en/brands/repco/repco-cv-drive-shaft-nsa1038/p/A9496175 PAH Edited 08/03/19 10:15 AM by PAH Link to comment Share on other sites More sharing options...

On the one hand, I've had the since new and it's 10 years old. I'm not sure that I'll need to get another 10 years out of replacement Repco drive shafts. Not unless FG XR6T prices jump north like GTHO and XU-1 prices. On the other hand the last 10 years include standard running with the factory flywheel 270kw's. I suspect that the Pedders 700hp shafts will be heaps more $ than the Repco shafts on special tomorrow so I think I'll give the Repco units a go. Thanks all for your inputs.
