Front Diff Vibes ECGS bushing fix.

I just used amsoil severe gear 75w90. I am considering swapping to severe gear 75w140 now for the front diff though.

 

You can rent a driver set from AutoZone that fits for nothing(just a deposit but you get it back)

 

I'm running the same Amsoil

$29 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90 front and rear as I did before the bushing change. ECGS recommends the heavy gear oil for everything they do so I don't think its a specific recommendation because of the bushing and no one to my knowledge has ever presented any info as to why that would be the case. Use what you are comfortable with.

 

Somebody here did explain the mechanical advantages of running the heavier gear oil due to going from bearing to bushing but I couldn't recall where to find the explanation. Don't recall if that came from ECGS or one of the resident folks who was a certified mechanic. I went with the ECGS recommendation.

 

I'm certainly open to hearing/learning the advantages but I've not read anything credible and I think that includes the explanation post you are referring to. I strongly suspect that no matter what oil people choose to run we won't be hearing about any failures due to the oil.

 

After thinking about it more, I decided to go with

$29 75w-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75w-90 gear oil instead of the 85w-140, as the passenger side CV shaft uses a bushing and I haven't read of anyone on the forum having that bushing fail using either the factory 75w-85 gear oil or 75w-90 gear oil.

 

I just replaced one that had a different seal than the others I have seen. Might explain why some people see leaks after replacing them. It was a stock FJ and the seal was seated down in the housing. Pulled it and was getting ready to install the correct Toyota seal and noticed they were different. I then pulled out my spare skf seal and it was the same as the new oem seal. the FJ seal had a much longer outer lip and the sealing surface itself was further out than the current oem ones. So I installed the new oem completely seated and it pissed fluid, installed skf flush and it was fine.

 

Good question!

 

I just bought a 2005 bcsb trd sport. I have a constant vibration/hum, I have to check to see if it's in the wrong gear sometimes. The previous owner wasn't very good with tire rotations so they're a lil bit unevenly worn. I thought it was a wheel bearing when I bought it but they felt tight. It does it wether it's in 4wd or 2wd. Does this sound like it could be the needle bearing even if it does it in 4wd and 2wd? Could the tires really be causing this? They're definitely not worn correctly but I didn't think they were that bad.

 

did you DIY or have dealership install?

 

I was getting new suspension installed and just had them do it.

 

Just had the dealer install my 3" lift on my 3rd gen. Went that route hoping they'll fight me less on warranty work. Anyway, I've got vibes now.... Has anyone had a dealer install the ecgs bushing? How was that process and what'd they charge you for it?

 

Pointless for me to really respond as I didn't have the dealership install my lift. Had a shop do it and figured I might as well do the Bushing as a safety net so the shop did the Bushing install as they did the suspension and didn't charge me at all for doing it. Probably cause they had 3 guys working on my truck.

Mine was the first 3rd gen they have worked on and have never done or heard of the ECGS Bushing before but after they watched the videos and tutorials on ECGS they gave it a go and it came out great.

Since you already have the lift installed by the dealer I honestly do not see why they wouldn't do the work. Idk if they warrantied their work on the lift, but if they did I don't think it should cost much if anything

Holy shit

 

That's just what mine look like

 

I give up, I've been trying to remove the CV shaft for over an hour with no luck using all of the suggested techniques mentioned here, so I'm going to give it one more shot in a little bit, and if still won't come out I'm just going to put it back together. WAPITFA

 

Did you try the pry a little and if not. Push back in and rotate a little then pry again?

 

try a long pry bar,or wraping a rope or cable around it then loop it and hit with a hammer

 

This is exactly why I just paid a shop to replace mine.
