Q: Will these work with the disc brake conversion kit #3005NETW?
⮞ 1 Answer
Answered by ☆ sales - January 22, 2025 00:47
A: Yes, these axles do work with the GM disc conversion.
Asked by Geoff, April 1, 2023
Q: Do you sell the dust shield/slinger that goes on the outer end of the INNER axles, or do I need to press them off my stock 77 axles and move them to these axles?
⮞ 1 Answer
Answered by ☆ sales - April 4, 2023
A: We do not offer a slinger for the inner axles. If your stock 77 slingers will fit, then you may use them. Otherwise, we leave the tubes open, so any debris that gets in, can get back out.
Asked by Daran Rumbaugh, February 6, 2022
Q: Are these axles the same diameter as stock where the slinger goes? I already have parts to rebuild my front Dana44 but realized that I need new axles, and would like to use my new, stock sized slingers. Thanks

Answered by ☆ sales - February 7, 2022
A: Yes, these use the same stock Dana 44 slingers on the stub axles. Like our #8860.
Asked by William Richard Lay, February 23, 2020

⮞ 1 Answer
Answered by ☆ sales - February 24, 2020

Asked by Clint, June 10, 2019
Q: Will these fit a 1969 Ford bronco with a Dana 30?
⮞ 1 Answer
Answered by ☆ sales - June 11, 2019

Asked by Jack, May 8, 2019
Q: Will these axles fit through drum brake knuckles ? or do you have to remove knuckles to install ?
Thanks
⮞ 1 Answer
Answered by ☆ sales - May 8, 2019
A: Typically the axles will fit through the hole in the 6 bolt drum knuckles. We have had a couple folks have to clean up the casting on the knuckle in a couple instances. Usually, it is not an issue. We are not aware of anyone having to remove the knuckle.
