What seal should be used for running the ELHS, Would using the stock 1G fwd axle seal cause a leak?

Parts needed:

• AWD intermediate shaft
• AWD Drivers side axle
• 1 MD707184 1g FWD output shaft seal
  
• 2 MB297860 Bolts which attach the intermediate shaft to the block
• 2 MF450406 Lock washers for the above bolts
• 1 MB297732 Spacer which is only needed if A/C compressor bracket is removed
• 2.3 quarts of transmission fluid (SAE 75W-85W gear oil was recommended from the factory)(Redline MT-90 is recommended by most DSM transmission specialists).

right i have read that but does the fwd axle seal cause a leak because the awd half-shaft seal is totally different

It's totally different because the transmission case is totally different. You're matching the seal to the transmission, not the axle.

yes i get that, but the half-shaft is a straight bar compared to where the stock fwd axle has cups on both ends that's why they used different seals


this is from Vfaq



Q: So why do I need this spacer kit? Why can't I just use a new FWD transmission oil seal?
A: We said and tried the same thing. But there are a couple of problems with using a FWD oil seal:

We tried 3 different FWD seals, but the axle still leaked. The axles measured extremely close in size, so it is not an axle difference.
One major difference is that the AWD seal has three sealing surfaces while the FWD only has two, and the AWD seal surfaces are angled differently. The FWD seal is designed to have a CV joint pressing against it, unlike the AWD, and that may factor into how the seal surfaces align on the axle shaft.
The FWD oil seal has no dust cover like the AWD seal, so dirt / fluids have a much better chance of getting past the seal into the transmission.

I used the stock FWD trans seal and it worked fine.

I used the fwd seal for years without issue on my old gst. Have since moved onto awd but the guy who has it now has never had an issue either
