Transfer case noise/problem opinion
My Evo is an '03. I had a local mechanic install an RRE LSD and replace the 3-4 synchro late in 2006. There was no gear noise prior to the work.
When I got the car back, on deacceleration against compression, it made (and makes) a noise that I describe as a bell being cut with a buzz saw. The sound is loud when slowing down from 45-50mph in fourth against compression, lesser at lower rpm and slowing force. I believe the noise is gradually getting louder.
You may wonder why I didn't take it back to the mechanic immediately. I tried, but he was ducking me. Soon afterwards I was away for a couple of months and have been very busy since. I still try and reach him hit and miss, but no luck.
There are no new sounds on acceleration. The car is a daily driver that I track several times a year, plus one hillclimb, so I exercise it through most conditions.
When I read about transfer case problems on EvoNet, the noise is usually described as a whine. Questions:
Does it occur on acceleration?
Slowing against compression?
Both?
Has anyone experienced the hollow, almost ringing noise slowing on compression, but no unusual noise on acceleration?
If you have had the symptom described in the last question, how did you solve the problem?
Thanks for the help,
