I see what you mean where - Polishzx 15:19:04 02/15/24 I just did my rear traction arms with whiteline - komplexZTT 05:00:50 02/16/24 Don't not recommend (n/m) - Bernie (NoVA) 20:01:50 02/16/24 Those Whiteline W62546 will fit in - Polishzx 14:28:17 02/21/24 Gordon had noise and failure issues with Whiteline. - Bernie (NoVA) 20:13:49 02/16/24 There is still the benefit that poly bushings are harder - Polishzx 14:51:32 02/21/24 They will be noisy. It's bad idea to use them. (n/m) - Bernie (NoVA) 18:34:49 02/21/24 What do you recommend for subframe bushings Bernie ? (n/m) - Z-speed 11:50:46 02/22/24 If you have to replace stock, black ES I guess. - Bernie (NoVA) 22:52:53 02/23/24
