Translated from the original English below (sorry, I'm still learning German). Vehicle details:
Nissan Qashqai +2 (aka Rogue) 2010 2L petrol 6spd manual 4x4. 130,000 km odo.
Symptoms:
So that they started (a few months in between).
1 Intermittent clapping noise immediately after engaging the clutch from a standing position.
2. The front left axle diff seal began to leak. Shortly thereafter replaced by Nissan.
2. Usually difficult to shift into 1st gear (often a dual clutch has to be engaged in order to engage), sometimes a little difficult to shift into 2nd gear. The same whether in 4x4 or 2x4.
3. Intermittent vibration at ~ 50 km / h, not at higher or lower speeds. The vibration remains the same regardless of gear selection or engagement of the clutch. The same whether in 4x4 or 2x4. The steering doesn't seem to do it either.
Based on the symptoms and discussions with others, I was confident that it was a transmission problem. Since I live in Switzerland and the labor costs are high, I changed the gearbox myself (with the 4x4 transfer case included) 3 months ago in a DIY workshop. I followed the Nissan service manual. The replacement was used with ~ 80,000 km. At the same time I installed a new concentric slave cylinder for the clutch. I bled all the air out afterwards. New diff seals too.
During the exchange, I didn't notice any issues with other parts.
Initially, all gears changed slightly, but within days of the change, I notice the clanking noise after I put the clutch back on. No diff seal leak yet, but shifting is again difficult and the vibration occurs occasionally.
Since they were relatively cheap and quick to change, I foreshadowed both front wheel bearings. No change in symptoms. All CV articulated boots are in good condition with no evidence of grease leaks. I pulled back the inner CV boots to inspect and there is a lot of grease in there. All engine mounts look good. The right front axle bearing appears to be OK. The cardan shaft bearing appears to be OK.
Since it was idling on the hoist in 1st gear, I couldn't see or hear any problems.
Given the symptoms and the fact that it is a 2nd gearbox (and a 4x4 transfer case) with the same symptoms, I can't think of anything other than the following:
1. CV joints of the front axle (most likely inside left).
2. Front bearing of the right axle support.
3 propeller shaft. It continues to spin when set to 2x4 as the 4x4 engagement is at the rear.
Can any of these points cause problems when shifting the manual transmission?
Are my symptoms clearly pointing to a cause?
Am I missing other possible causes?
If it is a bad CV joint and I am installing new axle assemblies, it could possibly solve all of my problems or is it certain my 2nd gearbox is damaged?
I'm tempted to swap both front axle assemblies, but only if I'm sure it will fix the problem. It could also be the cardan shaft. According to Nissan, the propshaft and suspension bearing cannot be serviced separately, and I don't want to replace the whole thing without evidence.
I appreciate any help you can give. Many thanks.
Car details:
Nissan Qashqai +2 (aka Rogue) 2010 2L Petrol 6spd Manual 4x4. 130,000km odo.
Symptoms:
In order they started happening (a few months in between.)
1 Intermittent clunk noise just after engaging the clutch from a standing start.
2. Front left axle diff seal started leaking. Replaced by Nissan shortly after.
2. Usually difficult to change into 1st gear (often need to double clutch to get it in), sometimes a little difficult into 2nd also. Same whether in 4x4 or 2x4.
3. Intermittent vibration at ~ 50kph (30mph), not at higher or lower speeds. Vibration remains the same regardless of gear selection or clutch engagement. Same whether in 4x4 or 2x4. Steering doesn't seem to effect it either.
Based on the symptoms and discussions with others, I felt confident it was a transmission problem. Since I live in Switzerland and the labor costs are high, I changed the gearbox (with included 4x4 transfer case) myself at a DIY workshop 3 months ago. I followed the Nissan service manual. The replacement was used with ~ 80,000km. I installed a new clutch concentric slave cylinder at the same time. I bled all air out after. New diff seals too.
During the replacement I didn't notice any problems with any other parts.
Initially the gears all changed easily, but within days after the replacement, I notice the clunk noise after engaging the clutch again. So far, no diff seal leak, but shifting is difficult again and the vibration occasionally happens.
Since they were relatively cheap and quick to change, I replaced both front wheel bearings on a hunch. No change to the symptoms. All CV joint boots appear in good condition with no signs of grease leaks. I pulled back the inner CV boots to inspect and there is plenty of grease in there. All engine mounts look fine. RH front axle support bearing seems ok. Prop shaft bearing seems ok.
With it running at idle in 1st gear up on the hoist, I couldn't see or hear any problems.
Based on the symptoms and the fact this is a 2nd gearbox (and 4x4 transfer case) with same symptoms, I can't think of anything it could be except the following:
1. Front axle CV joints (most likely inner left).
2. Front RH axle support bearing.
3 propeller shaft. It continues to turn when set to 2x4, since the 4x4 engagement is at the rear.
Can one of these items cause manual transmission shifting problems?
Do my symptoms clearly point to 1 cause?
Am I missing some other possible causes?
If it is a bad CV joint and I install new axle assemblies, is it possible all my problems could be solved, or is it certain my 2nd gearbox is damaged?
I'm tempted to change both front axle assemblies, but only if I'm certain it'll fix it. It could be the prop shaft also. According to Nissan, the prop shaft and hanger bearing are not separately serviceable, and I don't want to replace the whole thing without evidence.
I appreciate any help you can give with this. Thanks.
