88 GXL LSD a simple swap into an S5 vert?
I did do some searching, but couldnt find a definitive answer. I have a 90 S5 vert that has the factory 4.10 rear end, non LSD. I want to swap in a 4.10 LSD rear from an S4 GXL, but im not sure if i have to change the drive shaft and axles. Anyone?
I believe that because the GXL was an N/A, and that because the gear ratio is the same, that i wont need different axles, but im not sure if the GXL had larger outputs where the axles bolt up. Can some one help? Thanks! |

Yes.You can replace the Open diff(whole unit) with an LSD Differential.You do not need to go Five lug..the Half Shafts are the same whether it be an Open Diff/4 lug ,or an LSD/5 lug..but the TII LSD will have different Shafts all the way around(Drive shaft and Half Shafts).

All FC nonturbo diffs swap directly into all other FC nonturbos, but if the gear ratio in the diff is different from what the recipient car came with then your speedo will be off (unless you change the speedo gear in the trans as well). Auto 86-8 GXL's would have had the 3.9 LSD, while manual 86-8 GXL and 88 GTU would have had the 4.1 LSD. 89-90 GXL/91 coupe did not have LSD. 89-90 GTU-s (not plural of "gtu" but model "gtus") had the 4.3 LSD.
The turbo LSD diff is different and not compatible with any NA fc parts. Never mind^^^^ after more specific searching i believe i found my answer, but others are more than welcome to comment on it. |
Direct swap, no need to change anything.
