I rebuild my tranny because it make noise when the car deceleration with 1 gear and 2 in.
My mechanic found that the first and the last bearing of center shaft is damage.
The problem is that mazda didnt have it in stock and I have to wait about 3-4 weeks so I would like to ask if someone have replace oem bearings with skf.

 

FYI -
This info if from my archives from the old "big list" not sure of the original source of this info but I know it is at least 6 years old. I'v had no personal experience with the referenced "aftermarket" bearings.

"I was having trouble deciding between a bearing kit from NOK or the parts from Mazda. I went the Mazda route and I have a parts list for those of you looking to go to a bearing house."

Mazda PN *********** manufacturer PN
R501-17-204 ********** NSK TM 3/32
R501-17-295 ********** NSK TM307
R501-17-290A ********* NTN NKI 255820-5NR
9960-66-3563 ********* NTN 63/28C3
M505-17-306 ********** NSK NTF 025-57
R521-17-299 ********** NTN TM63/22C3

 

SKF was and maybe still is one of the biggest bearing manufacturers in the world and although I have not had a chance to use them on my FD, I've had great success with them since the late 1960's. Make sure they are genuine though since there are a lot fake autoparts around.

 

Thank you for answer me
Finaly the news is that I have to replace all the bearings from my tranny so I will buy skf bearings.I hope to find all the bearings in skf otherwise I have to go from mazda and wait about 30 days.
